I needed a coaster holder for all these fun coasters I was printing. The first one I printed from a file online was flimsy and cracked. Thus, I decided to design one that was more practical and a bit sturdier. I added the slant not only for aesthetic purposes but also to allow me to print it without needing supports.

The base dimensions are for 10cm diameter coasters (the internal diameter is 104mm). You may need to resize the X and Y depending on the coaster size you have at home.

The picture is from a print on my Prusa MK4S on silk silver PLA which handled the overhang quite nicely without supports. I also tried printing it on my CC, but there was some visual drooping of the overhangs (not bad, but noticeable when viewed from the side). Thus, even though I added the slant to avoid needing overhangs, you may need to print with supports depending on your printer.
