I liked the scraper design by ncsandor but I saw a few issues with it which I wanted to improve upon.

Fillets

Using fillets on the Z axis never looks as good as chamfers when it is printed. Also the fillets on the bottom of the original print didn't leave much surface area for good bed adhesion so I remade the model with chamfers all around

Supports

The original print would have needed supports since the inside is hollowed out, I put 45° chamfers on the inside to reduce the overhang which should allow for printing without supports.

Rigidity

Part of the change I made to eliminate the need for supports was to add a center beam which will also increase the overall rigidity

Hex Hole

This change is minor but the hole on the original was nearly 10mm hex so I made it exactly 10mm so you could use it as a wrench if you needed to

Logo

I threw my name on it instead of Prusa while I was at it. I make music and instruments under the name Schreibmaschine.Berlin. You can suport my work on Patreon (via the link in my profile) to get access to more high quality prints and synth designs.
