Had to upload as a 3mf as the stl wouldn't save right out of the slicer where I edited the model. I have printed it on my modified Ender 3v2 with a brim and it prints fine. The clean up isn't ideal, but it works. Tried my Prusa MK2S and needed a raft as the brim was too hard to remove cleanly.
The author remixed this model.
Filled in the body and added a negative space to fit a #2 pencil eraser.
