Creality Bearing Spacer

thingiverse

For those too time-poor or lacking the tools to design, this is a simple spacer to fit between the bearings in the rollers on Creality Printers. It's 1mm thick, with a 5mm ID and 8mm OD. Creality, unfortunately, seems to have a number of these bearings with spacers that are too wide - approximately 1.5mm. As a result, despite how tight the bearings are within the rollers there's the potential for them to slide side-to-side, causing alignment issues. This is most noticeable on the bed, especially if your print sticks, since it can cause levelling to be thrown out after removing a print, but can also be an issue on the gantry. Since it should be exposed to almost zero friction and heat you can use any non-flexible material you please, but use a layer height which is a factor of 1.0mm for best results.
