This is a replacement support for a drawer rail in our motorhome. It seems like I need to replace one of these every year, so I thought I'd make one out of ABS and see if it holds up any better.

Edit:

The original version of this was slightly off in one dimension, so I re-sized it and added the new files with "_corrected" on the end.

If your motorhome is similar to mine, the STL file might work for you. Just print and go. If not, I provided the SCAD file so you can modify it to suit you. Sorry, it's not commented at all, but it isn't too big, so you can probably figure it out yourself. The toughest part was getting the inlet of the slot to taper for ease of use.
