DodecInABox - Dodecahedron trapped inside a cube - Prints in place

thingiverse

This is a simple printer torture test I created using a CAD program. Native resolution shows the cube measures 60mmx60mmx60mm. Printed example shown has been scaled down to 20mmx20mmx20mm within CURA. This can test overall dimensional accuracy, ability to print and remove supports, bridging, and vertical angles without support below 50 degrees. The dodecahedron is large enough inside for rotation around in all three dimensions, but elbow room is cramped. The inside shape that the dodecahedron is trapped within is a sphere. I printed the example shown at .2mm layer height, with CURA support only touching the buildplate - so it has a few areas that technically need supports, but really only the bridges at the top of the Y axis openings are any worse off for it. The only support absolutely needed is below the dodecahedron which is centered in the cavity and needs about 2mm of support (if you scale the full model down to 20mm overall size). You can also print it with full supports at 50 degree overhang, and your bridges will be supported. It's a satisfying little fidget toy that makes a sound if you hold it by two points and blow through it tangentially. Printed in 51 minutes on my Ender 3. I included the GCODE files because I thought why not. The bed was at 60, and the nozzle was at 220 - that's just how I do things.
