Barbell Bushing

I saw a similiar design but it did not work for my power rack. So designed a small spacer for storing my Barbell when not in use. Very simple, I have M12 holes, so can use M12 bolts, the problem I found is that the bolts as our local hardware store were to short, so managed to find M12 threaded bar that way can cut it longer and store on both sides or only on the one side. I printed these in PETG with 5 walls and 100% infill as was not sure how this would hold up in PLA. So far so good been a month of abuse and holding up well. Also please note I only use this for unloaded bars. Also if you look closely at the pictures the lower bar was thicker so used a square washer to ensure it did not jump off.
