Trumpet Repair - Dent Roller No.2

This is the first in a collection of different profile rollers to use in repairing brass musical instruments, specifically trumpets. At the date of creating this roller I have no dent repair experience but after many hours of examining old repair manual's and tool catalog's I decided to create these and teach myself. Usually made from polished steel, the entry price of these tools is prohibitive so i hope with careful filament material choice, careful printing and post printing polishing I can create a useable working library of tools and mandrels to share with everyone. The roller is designed to make use of 6901 bearings (12x24x6mm) on a 12mm shaft, all easily available parts from the usual online marketplaces.
