This is the Bubbloid223 puzzle.
This puzzle uses eight M3-0.50 screws however it will actually hold itself together without them. The screws I've used are 18mm long but anything 10mm to 18mm long should work just fine. You may purchase stickers for this puzzle here.
The finished puzzle weighs in at 144 grams and has 2 edge lengths: 74.2mm, and 65.2mm. This one was printed in White Strong & Flexible (the default material) and dyed black using Rit dye.
