Robin Hood, Alternative Top Cover for Prusa Core One Printer

Idea:

In the Prusa MK series, the filament was fed into the extruder from above. With the Core One printer, the filament is fed from the side through a tube. Changing filament is therefore not so easy, and the friction in the tube puts strain on the extruder motor. In addition, when doing manual multicolour printing, changing filament is made more difficult. So it also makes sense here to feed the filament from above. For this, the printer’s top cover plate has to be replaced with a hood.
The cover presented here, Robin Hood, consists of a printable frame into which 3 mm acrylic glass panes (or optionally plywood) are inserted. The side panes are bonded with silicone. The front and rear panes are simply laid on and have a handle. This way, you can remove these panes and have access to the space above the extruder. It also allows you to ventilate the build chamber.

Printed parts:

2x Corner LF / RB (Left Front / Right Back)
2x Corner RF / LB (Right Front / Left Back)
2x SidePart LF / RB
2x SidePart RF / LB
2x Top LF/RF
2x Top RF/LF
14x Nipple
2x Handle

Because of the heat in the build chamber, PETG – or preferably ASA – must be used as printing material.

Additional parts:

2x Glass pane L/R (see technical drawing)
2x Glass pane F/B
1x Cable grommet with brush seal (see pictures)
4x Screw M3 x 8
Silicone
