Blank cover DIN module for electric distribution boards, componible (1M & ½M) stv-is-it

Create the composition you need by stacking the modules.
The single module is 17.5 mm high.
The half module is 8.75 mm high.
Even after printing the modules can be separated along the prepared guides.
Good job.

Normally filaments are insulating but I recommend to use fireproof material (PCABS)
