Hi there!
This project is about enabling the Prusa MINI to clear its print bed after printing.

Features:
I have created custom 3D printable parts for this setup.
Printer Stand: It consists of 4 parts and can be assembled using 6 pcs of M3x16 screws, or it can even be glued together.
Print Bed Support: I have uploaded two different versions of this part.
Head Shield: Suitable for printers equipped with a V6 hotend.
Control:
The sweeping motion of the printer can be configured in your slicer by modifying the Machine End G-code, adjusting it based on the dimensions of your models.
This setup is suitable for smaller models and parts, which I have also tested. The Prusa MINI was able to sweep off models with an 18x18 mm footprint.
Warning: Do not print large models with this setup, as it may damage the printer itself!
Here is a timelapse of a test print.

This is only a prototype, feel free to improve it!

Happy printing! :D
