Brass Trimmer neck for Reloading brass

thingiverse

This is my iteration of a reloading brass neck trimmer. I made it with the user in mind, providing ample space for modifications. You can mount this to a drill or motor or hold the brass by hand while the unit turns. I created two main shaft holes, 7mm and 8mm, for gluing a purchased pilot onto a wood dowel. Mini Lathe owners can customize it further by making their own pilots. Both models allow the use of a 4mm square HSS steel or a 4x6mm HSS steel, as each opposing side has a hole for them. The retaining holes for the shaft and HSS are made to be tapped for an M1 6x0.35 bolt, but I made the hole smaller to 5.34mm to provide more meat when tapped. I also left extra material on each hole to drill out and use any bolt you wish. The design reduces finger slap and looks great. I hope you enjoy it and share your project with others. Please give credit where credit is due, as this design belongs to me. Selling this for profit is not allowed, and distribution on commercial or eBay platforms requires my consent first.

I printed this with PETG material at 20% infill, but the hot end was too hot and moisture was present in the material. It prints much better at 10% infill. The print time is around 2 hours. Please give me your feedback - I'm always looking to improve!
