Multi-function test cube

thingiverse

I wanted a straightforward and fast-to-print test to refine many parameters, so I created this. This isn't intended to push your printer's limits, but rather find a "good enough" balance. These are some of the things I can test with it: Dimensions: The basic cube is 20mm in size, the holes are 10mm deep and the well on top is 16x16mm inside with 2mm thick walls. Layer adhesion: Use pliers to break off the upper wall or insert them into the round hole trying to pry the block apart. Stringing: If stringing is an issue, you'll see it in the holes and/or the well. Ringing: It could be visible around the holes, corners, or dimples around the well. Surface smoothness: Both walls and top layers are easily visible. Loose belts: Look for weird artifacts around the rounded corners. Overhangs: The overhang on the outside is straightforward, but the round hole might be a bit more challenging, though not impossible. Bridging: It's mainly tested by the square hole. Let me know what else you can test with this simple print. Designed in OnShape: https://cad.onshape.com/documents/b278982bdf8aa44b7bf4ae93/w/856541142d3cd3b8c6950523/e/c988254dcece2c47b9786b2c
