coater ikea organiser

I was tired that all the coaster from ikea are lost in the shelf so i design a simple ordering tool to place them nice on place.
This part speak for himself, if you have the same coaster from ikea and you want some nice shelf print this part. I make it as light (and cheap) as possible.
There is room for at least 6 coaster maybe 7 or 8 will also fit.
The coaster is quit tight if you want to put away the coaster, but they fell over by themselves. If you want some more room you can re scale i
