Compass for riichi mahjong. Slot is for standard scoring sticks (65 x 7 x 4 mm). Tiles on the picture are AMOS 28 mm (28 x 21 x 16.5 mm). You can make compass bigger or smaller depending on tiles you are using. Compass size is 130 x 130 x 5 mm.

This is multi colour print. Letters are only 0,2 mm deep, but you can also slice it with 0,3 mm layer height. I would recommend to print in grey (I didn't have it), because if printing in white riichi stick and compass are the same colour and you can easily forget to take the stick after the win.

Print settings:

• When importing 3mf or stl, make sure you “split to parts”. This will make it easier to do multi colour print.
• 0,6 mm nozzle with 0,3 mm layer height.
• 15% or more infill.
• 2 perimeters.
• 2 bottom, 4 top full layers
• Wipe tower - no sparse layers will purge some filament only on change. Tower height is 0,6mm (make sure you have enough clearance between nozzle and printed model).
• Try printing on rough surface. I printed on glass and the compass slides when there are only few tiles supporting it. It is stable after 1st line of tiles is filled.
