STL and STEP files (made from original .stl files) included.
Notes:
I printed top parts with 5 perimeters (ie. arms printed without infill). I recommend to use raft for Top part because end of arms (or use the mouse ears at the end).
The author remixed this model. Imported from Thingiverse.
Original bottom part is changed to “stand” version.
Top part has thicker side arms and I removed overhang (I didn't know purpose of it :-D).
