I've designed this very simple tool to keep the door wide open while doing maintenance of the printer.

Printing tips :

• Layer height: 0.2mm
• Wall loops : 3
• Bottom and top shell layers: 5
• Sparse infill density : 15%
• no support needed

Filament :

• about 1.96 m of META PLA, Hyper PLA or PETG.

Material :

• 2 M3×8 hex cap screws (thanks to Colin for confirming that the original screws are too short).
