What type filament did you use, i.e PLA?
I have to start learning CAD AGAIN! Finally found a tutorial I like. I tried using PTEG just before my gf took over my printer area and couldn't get it to work right. Another one of these days project.
PETG is a little more complex to deal with since it is running a higher temp and requires a heated print bed to not warp. Look into PETG + as it has a lot of the same properties of PETG but less hassles.
What CAD program do ya'll use for 3D modeling? I'm in the process of learning FreeCAD which seems to work.
I just got a Crealy 6 myself and use PLA since that's what came with it.
I had the same problems in trying to to understand the programming. Tried a lot of different tutorials but just got frustrated. Found one made by "Make with Tech" and things finally started to click. I am going back to his videos to refresh what little I learned and to hopefully finish one video. Good luck.

The quickest, easiest modeling tool is Tinkercad. You can get up and running in about 15 minutes. FreeCad (as you know) has a much steeper learning curve. Of course, Tinkercad has less features, but it is awesome to get started.
I have used Tinkercad up until recently.
The problem with Tinkercad is the resolution.
When you try to print something that’s a circle it looks more like a polygon.
I’ll post up a couple of things I printed off of Tinkercad compared to fusion and you’ll be able to see right away what the problem is especially for anything that needs some precision.
The guy I referenced above started by having you look at tinkercad to get you thinking the right way then went on into freecad.
I'd be interested if someone designed the rest of the bullet feeder.

I have and use Autocad everyday in the Construction industry for 50 years, designing and building all kinds of Architecture. But I never hardly looked at 3D. In fact I wasn't that sure it could do it very well. Then I got a 3d printer. Was like starting over.
Not knowing much, I decided to download and tryout Fusion 360.....which was great, but with Autodesk having me for a commercial customer, I could only do it free for a month. Then they wanted to charge my commercial account, a lot of money. So I removed it and started looking seriously at the Autocad I have already. I found it could do anything Fusion 360 could do....what a shock! Good thing too, because with Autocad training, I would have to unlearn every Autocad command and start totally foreign commands that were like learning to speak Chinese. But there was still a problem......the bullet collator thread here! Ammo Mike and TylerR and RedlegEd use software just as foreign and incompatible to learn as me moving to China.
They use Openscad, a programmers cad, and DesignSpark Mechanical (both free) to create all the Bullet Collator, and APP files in our Bullet Collator thread. Totally incompatible with Autocad. So I'm in the same boat as you guys.....but learning enough to contribute some.
If you are a computer programmer, do look at OpenScad, but whether you learn Openscad or not, either way look at DesignSpark. It is extremely powerful and free, and even better you can modify, to you own needs, all the files created in that wonderful thread here on Cast Boolits.....it's all about compatibility, so you don't have to reinvent the wheel over and over. I'm absolutely sure that you guys WITHOUT cad training can learn it faster than I can, not having all that Autocad in the brain.
I still print lots of 3d using Autocad, but I can only share the .stl files, which aren't alterable hardly at all. But if you learn DesignSpark Mechanical, that's a whole nuther world that opens up. Check it out, its Free.....and there's quite a bit of online help.
I have done top punches for my old Lyman 45 in PLA - thousands of bullets and have yet to have one wear out. PLA is actually stronger than PETG for parts that aren't exposed to heat.

Open SCAD is good for stuff like top punches because you can just change a couple of variables to get a new part.
