3D Printed Coaster in the shape of a wooden pallet! Make a few and see if your local bar or cafe would use them.

I originally designed the pallet to print in multiple pieces to reduce supports, but it's actually easier to print without supports and bridge the overhangs.

Best results for bridging with Wood PLA was 80mm/s at 200C. Higher temps like 220C sagged too much. Lower temps worked better!
