Simple coaster for vertically displaying your coasters. You can use the f3d file to amend things like the angle, gaps, depth and number of coasters. See the notes in the change parameters for more detail

The attached stl is for 4 x 6mm by 90mm coasters but you can use the attached f3d to create it for your own coasters.

Printed using standard settings - 0.4 nozzle and 0.2 layer height. Print with the base flat or you can try with the front down with supports but the supports can be annoying to remove.
