Lamp canopy - transformer case

This is a canopy for mounting and wiring home-made ceiling lamps. The LED transformer will be hidden.

Dimensions outside
170 x 85 x 55 mm

The canopy will be mount with 4 screws on a baseplate. There are 4 holes with a diameter of 3 mm.

The lamp holder can be mounted to the ceiling with up to 4 screws (hole diameter 5 mm).

To connect the lamp holder with the canopy, you need 2x M3 screws with length greater than 10 mm (i used 10 mm screws, but it will be much more easier with longer screws).

There are recesses for 2 M3 nuts in the lamp holder. These are very precise. It is recommended to pull the nut into the recess using the screws.

I printed it with PETG. Infill 20%. With support. PLA or similar should work the same way.
