Power Supply Housing (LRS-100-24)

I bought a stairway lighting controller (RL-Step-02) which came with the LRS-100-24 power supply. The model for the RL-Step-02 controller I've uploaded here:
https://www.printables.com/model/1040558-rl-step-02-stairway-lighting-controller-housing 

The power supply has open, touchable connections which is too dangerous to simply mount it to the wall.

To prevent touching it I have created this case including some slots for heat regulation. It can be mounted to the wall after mounting the power supply. It has enough room for all connections and also 4 holes. One is to connect the output power to the device (in this case the RL-Step-02 stairway lighting controller), one is for the 230V power cable and the two smaller holes at the bottom can be used to fix the power supply to the case if desired.

The SKP file contains the design which also contains a 3D model of the power supply for better view. This model is not from me but also not to be printed. This file is from here:

I converted the STP using FreeCAD to STL and imported it to the Sketchup file.

Printing

As some of the slots are in the vertical wall I added tree support (also support is needed for the mounting clips). I think, OrcaSlicer creates too fast movement by default so it destroyed the tree after some layers. Because the clips needed the support I paused the print and added a foam “help support” which saved my print.. :)

So I recommend: Don't use tree support here, better should be normal support. Use support painting to remove support for the slots in the vertical wall because if you enable bridging this works without support.

In all cases better to setup the slicer to print slowly at least for the walls.

Nevertheless, it printed and the result is good enough.
