Just a monkey butler so you can focus on designing prints. The bed is originally for mk3 from here.
To add it, go to printer settings → General → Size and coordinates → Bed shape → Set → then in “model” load it!
I also included .scad file for who wish to modify it further, but remember to simplify the original monkey as to not slow the slicer.
The author remixed this model.
Simplified, then resized, and added mk3 bed.
