I always have bad feelings when I print overnight. That's why I designed a holder for a smoke detector from ABUS: ABUS RMW150

The smoke detector hangs directly above the print bed, so it can react very quickly in case of firer.

Assembly:

1. Put the “holder.stl” and “base.stl” together
2. Cut the included screws in a lenght of approx. 6-6,5 mm
3. Mount the ABUS holder on your printed part
4. Mount the smoke detector on the holder
5. Simply clip the holder on the aluminium frame of your A1
6. FINISH :-)
