RL-Step-02 Stairway Lighting Controller Housing

The stairway lighting controller RL-Step-02 I found on Amazon to illuminate step by step the stairs. That looks very good - but it is delivered of course with a lot of cables and with a not very nice power supply with additionally dangerous touchable connectors.

So I made two housings, one for the controller to hide all the cabling and one for the power supply to make it safe. I've also uploaded this here:

As the cables must come out somewhere there are two rectangle holes at the top for the cables of the left and right side of the controller (2 x 8 cables on each side). To hide them, the holes are rectangular and a standard 15 x 30mm cable tray can be used like displayed in the Sketchup title picture.

I used the model here for the cable tray, but they are not part of the model here, only for demo purposes in the Sketchup file:

I've made a 15x30mm variant out of this model as there was none in this size.

You can see in the final picture how it looks like after mounting it to the wall.

The hole in the middle is for the LED display of the controller which is useful when you need to setup the different modes. Also the buttons can be handled if you don't know where you have lost the remote controller (and if you didn't want to use the wall mount)… :)

The round hole at the right side is to connect the controller with the power supply. For that reason the same hole with the same size exists on the power supply housing so you can mount both close to each other if you want (and for that reason the fourth mounting clip is at the top and not at the top right side). 

Printing

Don't wonder why the housing has a grey line at the bottom in the photos - I simply ran out of white PLA and grey seems to be a good replacement… :)

Support is needed for the outer cable tray holes.

The walls of the model are very thin, so it is not very stable. But it don't need to be, should only be an optical cover. If you want, you can resize the wall to at least 2mm more to have stable walls.

The print was made on a Snapmaker A350T with white/grey Sunlu PLA+ filament.

Mounting

The clips are a bit thinner than the ones from my power supply housing. Nevertheless strong enough. To mount it, first mount the controller to the wall as everything needs to be aligned to it. Then hold the housing over it and align it so that the buttons and the LEDs can be seen through the window. Now you can align the cable trays and screw them to the wall so everything will fit later. Remove the housing, insert all cabling as needed and put the housing back over the controller. Check again to see that the buttons and their labels can be seen and also the LEDs and screw it onto the wall.

(My power supply housing was a biiit to close to the controller housing to easily use the plugs. Better to move it a bit away. Or just remove the plugs and directly connect the power supply with the controller, then you can also mount the power supply housing close to the controller housing. Align the two holes of both housings at the right/left side of the housings for that purpose.)

If possible, you can use the power supply housing also to cover the electric 230V cable which was not possible in my case. Need to add an additional housing for that.
