About this 3D model

hello? I needed an external spool guide, so I printed the original Ultrajaxel's External Spool Holder and Guide. But the parts on the roller part did not fit, so I processed it several times and was not satisfied. so I referred to another one and made one. The original filament was made of ABS, but I used PLA. I think it may have been designed with the shrinkage of ABS in mind, so it did not fit PLA. The width is designed to be 80mm and there is a gap of 0.4mm from the bearing.
