Hi… I am the proud owner of a Tevo Tarantula 3d printer, my first 3d printer, and I am running out of things to print! I have upgraded/modded my printer all over the place and my models look pretty darn good. The first tw9o prints I did - the xyz cube and the obligatory benchy - looked better than a lot of the models I’ve seen posted by “seasoned experts” so I am really happy with my little spider. I came across this and found that there are very few hubs listed in my area and only one within a 40 mile radius. Can anyone be a hub? Are there any requirements or qualifications? I can post a couple of my best prints to show mine and my printers abilities. I have even been designing my own models (a nice little case for the Tevo electronics is very popular - well for me anyway - on Thingiverse)… Any help or advice would be great.

Hi,
Welcome to 3D Hubs, all you need to do is apply for listing your printer as a hub and follow verification steps
Then orders should come automatically.
If orders don’t come too quickly, then ask your family and friends to order some prints from your hub so they can leave some positive feedback in order to attract new customers,

And your test print (your first “order”) is Marvin, from a staff member of 3D Hubs. If you want top marks, practice printing Marvin before your first test order (get him from Thingiverse) and get him printed perfect at 100 micron layer height.
Best of luck!

P.S. You need to upload some pictures of your perfect Benchy and Cube to show off your skills to us!
I don’t have any of my cubes with me right now, but I have a few models I can show off. The marvin is without any cleanup. I assume that when printing for clients, cleanup is expected?
So… do they look like I might could make the cut as a hub?
Yes definitely, it looks like you have a tiny amount of over extrusion but that can be easily fixed by calibrating E steps/mm
Yeah, you’d be a great “Hubber”. Agree that the prints look like they are over-extruding a little. Maybe check the steps per mm for the extruder is correct, or test another print with slightly less “Flow” in the settings, from 100% to 98/97% and see if that makes less “blobs and zits”?
Cleanup is expected to meet the FDM guidelines, to a point!

Welllllllll… I have calibrated e-steps a couple of times just to be double sure and flow rate is set to 90% now. Is there anything else that could cause it? My cooling fan is set to 75% because when I first installed it, it was creating a LOT of thin, hairy wisps due to the sheer force created by the 40mm radial fan. Could that have an effect?
The fan shouldn’t be causing the wisps - they are usually due to retraction settings… usually! One thing to take away with 3D printing - is there’s no one true answer, and almost every user setup if different, even with pre-built machines. Maybe try with the fan on full - best testing with smaller simple shapes like the classic 20mm cube to cross test two parameters - fan full, print, fan low, print… check, evaluate, repeat, pull hair out!
I finally managed to manage the wisps mostly with retraction, but I had to set that to 10mm! I will keep fiddling… luckily I enjoy a good challenge. Besides that, I’ve never owned anything, even items bought brand new, that I didn’t have to modify or repair so we’re all good Thank you for all of the advice.
