Bullet collator/feeder - updated

Complex model, gcode not included, as modifications according to your application are assumed.

For new downloads/builds use model version 7. Version 5 is kept for continuity.

Update available

New bullet plates design, new anchor and knob design (both left threaded). Complete rsdoc file, containing new elements (version 7) and new STL files, all having “new” in name are published with this update. The aim of the update is to eliminate possible issues if bullet jam occurs. Reflects experience of many working hours of V5.

Additionally, I use “electronic clutch” as part of the control unit to prevent motor stall in case of bullet jam in the collator.

Notes and other major components sample references:

1. Motor mount designed for JGA25-370 Geared motor DC motor 12V 5rpm ( https://www.aliexpress.com/item/32987942205.html )
2. Bullet drop adapter designed for:

• proximity sensor LJ12A3-4-Z/BY ( https://www.aliexpress.com/item/32859197984.html ). Model assumes thread cutting instead of printing for better accuracy. Sensor purpose is bullet counting.
• Mr.Bulletfeeder output spring Large for pistol calibers ( https://www.doublealpha.biz/mrbulletfeeder-output-spring-and-extension-adaptor ).

Print instructions

PLA and/or PETG according to your preferences. Use “mouse ears” (included in model) for Anchor part, no supports are required.
For large parts - eg. bucket etc., 0,2 - 0,25mm layer is OK. For other parts 0,2mm layer works fairly well.
For Bullet drop adapter, cutting thread was better in PLA (comparing to PETG) for some reason. Much better taper lead and cleaner thread.
