A 3D printed bullet casing sorter for separating 9mm from .380
All printed parts were printed in polymaker PLA+ with 3 perimiters and 15% infill. I used the "organic" supports in the latest alpha build of PrusaSlice https://github.com/prusa3d/PrusaSlicer/releases/ to avoid supports causing parts to have unnessesary roughness.
I printed the main sorter body oriented upright with the face of the .380 outlet down on the build plate. This gave me the best print quality results.

This project is not in a tested nor final form, expect things to change as problems are identified and addressed.
Here is a list of all of the non-printed parts I have used for this project:

Tenetive Addition: RC car shock absorber - https://www.amazon.com/gp/product/B0BLC4NCK9/ref=ewc_pr_img_3?smid=AJ0RJEXY6CYX2&psc=1
I am experiencing an intermitant feed failure where the case does not fall in time and gets mashed by the plunger. I have ordered a couple of these shock absorbers to replace the crank shaft to see if I can remedy the failure by allowing the motor to complete its rotation by compressing the shock absorber I hope this will additionally prevent the machine from breaking itself or from deforming the jammed case.
Please note that I made a decent effort to make things parametric and I definitly failed on the sorter body but I redesigned the enclosure so that it is fully parametric to endusre that people could easily swap in different power jacks, buttons, etc. with ease. I built mine using all parts I had laying arround from other projects and wanted to ensure that the greatest number of people could do the same.
M3 hardware is used everywhere expect on the motor. M2 is used on the motor both for mounting and as a cross pin to hold the wheel to the motor shaft.
I used a flat washer on each side of the crank shaft to reduce friction and use a drop of locktite to keep the nut from walking itself off. maybe I can work on embedding a nylock nut and shoulder bolt or something in the future but this is were its at now.
