Burr Stand for 2.4, 3.0 and 3.2mm Shank

I have a few drill burrs for cutting and grinding.  I wanted a way to bring all my burrs to a single place and neatly make them accessible.  An added complication is that the shank sizes are either 2.4mm, 3.0mm or 3.2mm (1/8in).

My solution to the complication is to have a modular burr stand parts.  The stands have the following capacities:
- 18 x 3.2mm shank
- 18 x 3.0mm shank
- 28 x 2.4mm shank
- 18 x 2.4mm shank

Each stand is 75mm wide by 15mm high.  Stand modules securely clip together, much like jigsaw puzzles to make a train like stand.

As I find more useful burrs, my modular approach allows me to just add a stand module that matches my burr growth.

My print is made in PLA 1.75mm Aurarum Gold filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer.  No print supports required.

I hope you can find this print useful, too.
