I needed a holder for my LED strip lights controller. I modelled it to be the exact size of the controller so it fits snugly and easy to put the controller in and out. 

I made it to be double side taped to the side of my unit but i've also included a seperate model which can be screwed in if needed.

I printed in PLA but PETG etc should work too.

Not sure the brand of the controller but seems to be a generic one shipped with most LED strip lights.
