Removing print supports has always been a challenge. There had to be a set of tools that would help, right? Everone has an x-acto knife and flush cutters, but is that all there is? Nope. I found a set of tools by a manufacturer I didn't recognize on Amazon (link). They work incredibly well, but came with a a plastic case that had them rattling against each other.

I've replaced it with a proper case designed in OpenSCAD. I doubt it will fit anything but this set of tools, but think the OpenSCAD script might be useful to others. (It uses the BOSL2 library.)

Parts required:

2 M3x20 screws (I used socked headed screws)

2 M3x6 self tapping screws (to secure the rubber bands)

2 (or more) rubber bands to hold things in

Note: the 3MF file provided does not include the somewhat incorrect label I've put on the case. (It's a modded Minecraft reference.)
