Ryobi String Trimmer Spool Holder

I needed a way to store string spools for my 18V Ryobi String Trimmer, so I designed my own. Most of the models I could find are meant to hold 5 or 6 + spools, but I only need a few of them and didn't want to waste all that filament to print such a giant piece. 

This one is super simple and can be installed with just two screws. The main piece has a hole that is .10mm larger in diameter than the rod, and when printed on my A1 with PLA basic, it was pretty much a perfect press fit. The rod itself is 80mm tall when pressed in, so it can hold 3 of the spools. I designed this to be press fit so the body could be mounted as pictured with two screws in the middle of the back plate, one top and one bottom, to keep it tight to the wall. I found that if I made the rod part of the model, then there would be no way to access those screws directly behind it, meaning I would need to put a screw hole in each corner of the back plate, which just seemed like overkill. If you think you will leave the item up permanently, then feel free to put some glue into the hole, but in my experience, if you press it in only once and don't take it in and out of the hole a million times, then it should stay snug. There's really not much tension on that rod if you're just lifting a spool on and off of it, so as long as you're conscious of it, you shouldn't have any problems for the life of the part. I only have the Ryobi 18 Volt string trimmer, not sure if it would work with other brands' spools, but feel free to try.
