10mm and 12mm Adapters for Lee Bullet Feeder

thingiverse

This design works seamlessly with both LEE bullet feeders and Open Bullet Feeders by AmmoMike. The component fits snugly between the tube after the spring and the bullet die. To enhance visibility, especially when working with darker bullets like Blue Bullets, a 12v LED is incorporated. The overall structure is designed to sit loosely in place. This part plays a crucial role in my OpenbulletFeeder DIY Bullet Feeder build, which can be found on Thingiverse at https://www.thingiverse.com/make:578974. UPDATE: Initially, the 10mm version was crafted with an intention to accommodate all bullet sizes smaller than 10mm due to the fact that 10mm bullets are slightly larger in diameter. I have subsequently created a 12mm version intended for use with 10mm bullets and possibly extending up to .458 bullets (.458 bullets were not tested). You can utilize the 12mm version for bullets smaller than 10mm, but there's a possibility they might get stuck by sliding sideways. It's recommended to use the 10mm version for smaller sizes and the 12mm version for larger sizes. If you require an adapter that is even larger, feel free to inquire about it in the comments section.
