The Grommet sitting sideways bothered me, so i decided to modify it a "little" bit.. 10 Prototypes later its finaly done (ugh took me half the day). Sits very tight but covers the hole perfectly, nice and flush. Little sanding on the bottom is needed.
Printed with ABS:
My Settings:
Layer Height 0,3 (0,6 Nozzle)
Walls / Perimeter 3
Top and Bottom Layer 3
Sparse Infill 30%
Infill Pattern Cubic
Infill / Wall Overlap 20%
Support Tree / Hybrid (not mandatory but will make the bottom cutout smother)
Enjoy
Update:
A User mentioned that the 3mf file wont open in Cura, so i added a STL Version.
The author remixed this model.
Slighty longer, wider and thicker, cutout on the bottom left so it slides in a little and a cutout on the top for the plastic piece on the left side of the screen
