I needed a guide for the barn door I made, but the commercial ones I found all extended too far into the hallway.
I decided I could design my own. It's printed with 15% infill from MatterHackers Build Series black PLA. I wasn't sure if the PLA would be strong enough, but I have had no problems!
The slight angle on the mounting side was to accommodate the existing door trim.
The author marked this model as their own original creation.
