This mount allows the Ryobi 40v Expand-it trimmer to be hung from the wall with the trimmer head still attached. The only holder that I previously found for the Ryobi was for the power head only, but didn't have enough space to allow the entire trimmer to be hung from the wall. This model is based off a wall mount for an EGO Trimmer that was modified by putting an angle on the end while still allowing the opening to be parallel to the wall. The opening was also made slightly bigger. 
 

I printed it in PLA with 5 walls and 15% infill.
