The original small plastic feet broke. I modeled and printed a couple of replacement ones; let's see how long they will last.
The 2 strip holders have to be pushed in place using a manual press or a vice. They fit very tightly (this is what I was looking for).
If they happen to break, drilling them with a 2,5mm drill should do the job.
I taped in M3 the holes of the chrome strip to add a bit of structure and friction but this might not be really necessary.
Print settings: PLA, 0.15mm, 100% infill, no support, 5mm brim.
EDIT: with my printer settings and filament the pin of the first version is too fragile. v2 brings more rigidity and ensures less torque is applied on the pin.
The author marked this model as their own original creation.
