Dụng cụ burnish da (Leather Burnishing Tool) dùng heat inserts

A leatherworking burnishing tool that attaches to a drill.

*You will need an M.3 or M.4 brass inserts (whichever works, I used M.4), a corresponding headless bolt, and a lock nut of the same size.*

To assemble:

1. Use heat to press a brass insert into the hole.

2. Thread in the headless bolt

3. Secure it using a lock nut.

For best results:

After assembly, attach it to a drill and spin it while using sandpaper to smooth it out.  

Print Settings:

I printed at 0.16mm layer using regular PLA, 4 walls, ten top layers, four bottom layers, and 10% infill. It feels very sturdy.
