Practical XL650 3D Printed Bullet Feeder

Actually, I misspoke, this guys video of a different design inspired me to pull the trigger on a 3D printer and build this:

I'll eventually print one of these too.

Also I said ether could work as a glue instead of weld-on, but actually what I was thinking was Chloroform, what kid nappers use. Glue as in the plastic melts and can be pressed together. Weld-on has a suspected carcinogen in it, Chloroform is a know carcinogen. At least that's what their SDS's say (if your company still uses MSDS's, time to report them to OSHA, if your in the USA that is).

I think the Pipe hangers were just under 2 dollars each.

Depending on print media, in my case about $10.00 for the plastic (PLA), $14 for the motor, $8 for the PWM motor driver, $4 for pipe hangers, had the 3/8" all-thread and nuts from work, and about $10 for Stainless steel M3 parts kit and lock nuts off Amazon, power supply was off an old unused battery charger.

I found a print resolution of 0.3mm was completely adequate. For the bullet drop spring adapter to hopper thingy 25% infill felt adequate, 60% on the bullet plates, and 100% on the hopper itself (60% too wimpy); but I would recommend that you live with the longer print times and stick with 100% infill on everything.

Design by blackice83, thank you sir!

PS - I mentioned the bullets might fall in the bullet drop/switch assembly such where the ogive does not quite activate the switch; in which case you would simply shim the assembly up a bit so that a bullet would activate the switch.
