wow that was fast

As I said quite some time ago, you can contact me via my hub and if you want to, we could agree on a pricing, that is within your requests. I stopped commenting for multiple reasons: (@Gabriela3d @Arnoldas you might want to pay some attention here, as that’s a general development, that I see frequently on talk) So first of all I don’t want to share finalized pricings in public, mostly because the chances, that somebody else comments, just to lower the price by 5€ is VERY realistic. What then goes on is best described by the term “passive rivalry” => nobody is insulting anyone, or talks bad about other hubs, but EVERYONE is willing to commit the last bit of discount possible, in order to get the job. This lowers the value of 3d modeling and 3d printing enormously and leads to the mindset, that customers can select any price they want, knowing, that there are hubs willing to fight for that order. 3d Hubs’ main purpose (to my understanding) is not to make the hubs rich, but at least it should aim to be a safe ordering method, that connects hubs and customers, it should also allow for reasonable prices. The customer should be able to chose and compare hubs and to pick the best for his job, but if the hubs take the action of comparing themselves to one another, then they will lower the prices in order to get the job, that might not even be close to worth the invested time. When this goes on, then lesser and lessee Hubbers will be able to compete with the pricing and will fade away from 3dhubs as it’s no way close to worth it (except for the community aspect of course). This future seems very pessimistic, but its, what I think to be realistic, so I try my very best to avoid this future. Next up I don’t want to be set on a specific price, especially in 3d printing there are insanely many variables to consider, starting at printing material and infill. I don’t want to promise the customer anything, when I can’t be absolutely sure, that I’m capable of accomplishing that goal. If some of those variables aren’t defined yet (like in your case the level of detail), then neither I, nor anyone else, will be able to precisely estimate the time investment and therefore the cost for the service.* Lastly there are some things, that I don’t want to discuss online, just for the sake of protecting privacy. In 99% of the cases there’s nothing that private about these orders, but sometimes a special request requires background information about the 3d printed part’s purpose.I don’t want to force the customer into talking out loud about that purpose. The best example would be, when the customer asks “what material would you recommend” as you might guess there are tons of different applications and so is the choise of material, in that case I’d need background information, otherwise I might sell the customer a highly inflammable ABS print, that he wants to use as cover for a torch. Oh and one last reason: Even though talk is a great place to communicate, I think it’s not the right place to have a 20 comments long conversation about an order. Everyone, that commented to this thread gets an email notification for EACH new comment. If we all would start to have our order conversations via talk threads, then the 3d hubs’ admins phones would light on fire from the frequent email notifications (same goes for people like myself, that are fairly active in this forum). So that’s it for now… I hope you can understand my mindset and argumentation, feel free to have a constructive conversation with me (maybe I should start another thread for this). Cheers, Marius Breuer *the only reason, why I said, that the charge for this model is within your budget for sure is, that I’m a hobby 3d modeler and don’t charge anything, like estimated working hours. I charge, what I think is realistic for this model, it’s up to myself, how fast or easy I can accomplish that. In this case I don’t think, that this model is worth more then your budget of 40€, so the charge would therefore also not exceed your budget. PS: i don’t know, if that was intended or accidentally, but please be so kind to only pay for orders, that are placed through 3d hubs. 3d Hubs has to financiate itself somehow and that’s just possible, if 3dhubs can charge a minor fee to orders, that are placed via 3dhubs (not just anonymous PayPal payments). In exchange 3dhubs gives you this forum and the guarantee, that you receive your model or get the money back, if the hub was failing for any reason. This of course can raise the cost a bit, but it’s worth the safety and should also be done just to credit 3dhubs for making all this possible.

ahh very sorry well I’m sorry if I seemed a little impatient this has been something I’ve wanted to get done for quite some time, plus irritability due to work and familial stresses tend to influence my impatience also I’m still new to how 3d hubs works so I’m at a bit of a loss when it comes to how things work here

A bit more detail!

Well, when you do something the second time, you don’t spend a lot of time figuring out how to do it!

46

That’s not your fault, just be aware of this in the future :wink: good luck with your project. Cheers, Marius Breuer

Marius

Thanks for commenting and clearing a few issues, and I agree with what you’re saying.

As I’m also fairly new to 3D Hubs, I now realise and understand that this should have gone through one of our Hubs rather than the lengthy public talk that’s been going on.

If MagusGunner wants me to continue with the cad, I’ll await a response via my Hub instead. If not, I hope he gets a suitable stl file of his project and eventually, good 3D Printing results.

Regards

Adam

I’ve drawn this up with reference to your photos and the initial image of the 4 silver rings! What do you think, is it close?

I’ve guessed the dimensions. It took about an hour in Solidworks.

More views to compare.

that’s true, well depending on who I go with for the 3d model I’ll contact the person directly to deal with payment for the commission

51

I also sometimes wish 3D Hubs just said “Ask for a quote!”. Ultimately I do business via private email and use 3D Hubs to finalize the order and the ease of use with PayPal. As far as material choice, I am not the designer of the part!

Anyhoo, if you just want a CAD design next time try CADCrowd. Much better why to get MANY designs! After you get a design there, come to 3D Hubs to get it printed!

Cheers!

52

any chance you could put the ring sizes on the inner part of the ring to help distinct the two when I do get them printed I’m more then likely going to have them printed the same color, just not sure on the material just yet

53

Done!

nice so I take it the models are completely done? but do you think you could make the numbers a little smaller?

55

you should definitely go wih high resolution SLS or SLA printers, they might cost a lot more to produce that way, but all the 3d modeled details are useless, if the printer isn’t capable of producting them.

Also why not use indication marks? an “X” for size 14 and an “O” for size 13,5 ? That would be way easier to see and would maybe come out in a lot more detail (would also be able to be made smaller).

Cheers,

Marius

that could work, but I’m not sure who has that type of printer, also I’m still unsure as to what material I should print it in, since there are a lot of different kinds of plastics

57

SLA printers can only print in resin, there are about 4 different resins, that you can choose from:

normal (mostly available in white, black, grey and clear)

tough (special purpose resin, which is generally stronger)

flexible (well … it can bend)

mold-making (specially designed to be used for metal castings)

High end printers mostly use some kind of Nylon (also called PA, which refers to the chemical name PolyAmide), this would work fine for the rings, it might also be available in full color, but then the 3d model requirements are much more complex and the cost stacks insanely.

Those machines are usually for industrial purpose, so the brands provide their proprietary material (in most cases), which will limit the choise to a hand full of materials.

The only method in which you choose between thousand different materials is the FFF or FDM printing method. This uses filament, that gets melted and pushed out of a tiny nozzle. Depending on the nozzle size the level of detail changes. However even the smallest nozzles aren’t 100% accurate due to the tolerances in the filament thickness, motion system, …

Also the temperature can’t be held absolutely accurate, it usually bounces between -3 and +3 degree of the desired value. This tiny temperature change can cause the filament to be more or less viscosic during different stages of the print, which can cause minor imperfections.

Lastly there are a lot of settings that have to be selected absolutely perfect in order to get a print with no surface marks, in most cases these settings also have to be adjusted for different stages of the print.

If you want to get those perfect prints with an FFF machine, then the chances are, that the hub needs up to 10 attempts to get the settings right, which makes this method as (if not more) expensive compared to the other methods listed above.

Additionally there are some SLS printers on 3d hubs. SLS stands for Selective Laser Sintering, which basically means, that a laser is welding your desired object into tiny layers of metal powder. As you might have guessed this doesn’t work with common plastics, but gives you 100% metal prints instead.

It might be worth a consideration, to have one of the rings made from brass, which would stay yours

…one ring to rule them all …

58

Any text can be added…but I agree, can the printer match the CAD?! Plus support material, etc. Find yourself a person to print and let them look over any model!

yikes I never knew 3d printing can be such a head ache, chances are I’d just want something in plastic that’s durable to wearing and won’t break easily on me, and I’d probably skip metal all together also wrong ring these aren’t for something from lord of the rings, honestly though I’m a little surprised that no one asked what they are for exactly other then for a cosplay

60

geeh yeah that’s a lot to consider
