Sand Belt Stand for Dremel 3000/4000

thingiverse

This is a straightforward tool that I designed for personal use, but can easily be replicated by others. It fits both Dremel 3000 and 4000 models (check file names to download it correctly). (WARNING: this was an experimental project. Dremels aren't ideal tools to use with it due to their torque limitations) In addition to the 3D printed parts, the following materials are required: * 1x Dremel 3000 or 4000 * 1x Sand belt 400x60mm (https://goo.gl/rejWYS) * 9x M3x10 allen screws * 2x M3x40 allen screws * 1x M3x30 allen screw * 9x M3 nuts * 3x Bearings 19x6x6mm (https://goo.gl/KLgNZr) * 8x Magnets 8x1mm (https://goo.gl/CFpL8S) * 1x Drill bit (3mm diameter) * Super glue or epoxy glue PS: the belt does not have a tension adjustment, as Dremel can't handle too much tension (at least in my Dremel 3000 model). I resolved this issue by cutting about 10 needle tips, heating them and attaching them to the cylinders (5 for each cylinder), leaving about 0.5 mm of clearance. This approach works well, allowing the cylinder to securely grip the belt.
