Pietro Grinder Base (first rough but functioning draft)

I bought a Pietro Grinder and I love it- what I don't love is the stability while grinding. So I made a base for it.
The design is very rough and unrefinded- but it works.
What helps is to stick some non-stick (like little rubber stops/a rubber mat or someting like that) under it since the base is quite slippery.

I printed it on an ultra-fast setting with around 15% infill.
