Beer coaster shelves

thingiverse

I wanted to print some modular shelves for my 3D printed busts, so i was desperately searching through platforms, and sliced a few models, but they were all ages to print and consumed a lot of filament, so i remembered my friend gave me dozens of beer coasters years ago, and since i dont use them i can upcycle them, and make my own shelves using less filament and less print time. The coasters are made of paper and their width are around 1mm (±0,1mm). The joints i designed are 18mm tall, and the radius is 7mm, the holes are 5.5mm deep and 1.5mm wide, 16mm long. The coasters fit perfectly with my settings, which u can see below. 1Piece take 12-13 mins to print, and 4/8 required to make a shelf (using 8 is more stable)
