This is a Heat Insert Mod of the great DIN Rail Bracket from Fabian.
M3 Heat Inserts up to 5.7mm can be used.
If you want to create your own mounts for it - hole distance is 52.5mm.
I will also publish several mounts I created.
2023-04-19: Due to request - 62.5mm hole distance version added.
The author remixed this model.
