roijeric's Printrbot Simple Spool Holder modified for smaller spools

thingiverse

I crafted an OpenSCAD script that slices up the core part of roijeric's spool holder and brings the corners closer together, allowing it to be used with spools smaller than the original 72mm in diameter. The "length" of the spool holder can also be adjusted, which might be necessary for spools with a smaller radius. I have included an STL file for 40mm spools, slightly shortened to fit a small printer's build volume. I left the feet unchanged from the original design; I've included the STL files for completeness' sake.
