Barbell Holder (Cradle) for Rack

Yesterday, I combined 2 of my favorite hobbies: physical training and 3D printing. When loading/unloading my barbell for deadlifts, the knurling on the bar wrecks the powder coat on my rack's bottom support. Additionally, I'm worried about the knurling taking a beating.

Enter 3D printing... I took a few quick measurements, whipped up a cradle that fits over the bottom support but with a little lip on the bottom to keep them in place, but still allow them to slide freely. They're printed in [carbon fiber PETG](https://atomicfilament.com/collections/exotic-specialty-filament/products/carbon-fiber-black-petg-pro) for now. If they don't hold up, I'll try [TPU*](https://www.amazon.com/dp/B00TI3JUTM?amp=&crid=1JN45DJ9I6JOG&amp=&sprefix=sainsmart+tp&linkCode=ll1&tag=etherbunny-20&linkId=1cab7ee65f660fd8f78daf02207c0f96&language=en_US&ref_=as_li_ss_tl) or use that as an excuse for trying to print in [nylon*](https://www.amazon.com/Polymaker-Nylon-Filament-1-75mm-Cardboard/dp/B09KKZ23VP
