Interlocking Coaster

thingiverse

People often use coasters that are designed specifically for stacking multiple on top of each other. The bottom pattern slots perfectly into the top one. I've had some problems with this particular model, as the corners tend to curl every time I try printing it out. This could be due to my printer's inadequate cooling system or the fact that I was using wood PLA material instead of a more suitable option. To improve print quality, I'll continue fine-tuning the tolerances and experimenting with different materials.
