PI - Coasters

In this instructable you can find 4 different coasters (different sizes/patterns/...) for your coffee mug.
You will find the 3D-designs, made with Tinkercad.
All you have to do is download and 3D-print them.

Due to some temporary 3D-printer problems I have not been able to print it yet.
I would love to see some prints!

Tips are welcome!
