When I wanted to light up my IKEA SKÅDIS pegboards using the IKEA ÖVERSIDAN I was surprised that nobody before me had created a mount for them. So, with no previous (S)CAD experience I made this my first modelling project and here are the results.
I've included the models I myself would had found useful previously, including two pairs of full on mounts for the angle and length I decided on, in addition to the base models for attaching to each side of the light bar, and the full blown .scad¹ file with Customizer support if you want another angle, another length, or just want access to the raw code behind it, it's yours to keep.
Build instructions
¹ You need to somehow have BOLS2 available nearby the SCAD file, or modify the file to point to an existing install of it, before you can make use of it.
The author marked this model as their own original creation.
