I've printed this Model with PETG
100% Infill
organic support
to mount the knob you'll need 2x M3 screws.
to mount the lid you can take a Nail (3mm diameter) and cut it to 40mm lenght.
for better fit, you can drill the holes to 3mm.
i took a spring out of a Ballpoint pen, cut it and bend the ends straight.
Then build in with a little tension.
The author marked this model as their own original creation.
