If you fitted Helia electrical boxes in your walls but they ended up to deep in the wall for your electrical switches/outlets to fit snug then you can use these risers/ophoogkaders to improve the fit.
Printed in PETG but PLA should be fine, moddeled these to be 5mm high and stackable.
The holes are made to accomodate M3 screws/bolts.
The author marked this model as their own original creation.
