Hi there! I’m not that experienced in making STL files, but here goes.
For a cookie cutter, the easiest thing I can think of would be:
1) On paper, draw out the sort of cuts you want to make
2) download Autodesk’s 123D Design
3) Using their sketch feature, draw out that shape on the ground plane
4) Use the extrude tool (might be called pull tool) and, well extrude all of it upwards in the z-axis.
5) Then if you have parts which arn’t exactly touching the outside wall of the cookie cutter, make some bars that join these together. (don’t forget to use the union tool)
This should get you a decent STL to try. I’ve only made simple STL files myself using 123D Design, but watching some tutorials has helped quite a bit.
Another thing to mention; If you’ve made a lot of cross bars joining itty bitty pieces, you might want to consider grouping the whole model together, and turning it upside down before exporting the STL. This way, those thick bars will be supported during printing by the bed, as opposed to being joined in mid air as you print. It also means you might be able to get thinner walls on your cookie cutter “blade” edge.
If you send me a 2d drawing, I could give it a shot. But just warning you, I’m pretty new to this stuff too
@kascejus really really really do it yourself in design software - you will get better and better after a really short time. Sketchup is a good place to start but the output can be buggy (not so good at producing manifold stls, but 123d will get you into the grove quicker and is great at stl output - have a loook at what people like James brunton do tih it in his ironaman cosplay on Youtube. For cookie cutters you needs a thick rim at the base (3-4mm thick) and then the wall as thin as you can get it - 1 or 2 wall thicknessess and fairly short as it is thin!
Ideally use XT or other ‘food grade’ plastic, and/or you ca throw it away, but XT is ok in a dishwasher. Start simple - do some stars of different sizes - and gradually work up in complexity. Recently I did a Llama for a party cracker
But the more you do yourself the faster you will get.
Ninja, thanks for reply. Really interested in your upcoming post, will be waiting for it to become available. A question for you: where and when do you teach the classess on 3D printing? I would be interested in participating and learning. Do you do your classess online? Thanks!
The post is up! I teach in Provo, Utah. Otherwise I will be making video tutorials in the near future. They will be on my blog: http://3dprintingninja.blogspot.com 4
