A great temporary replacement for the factory Glowforge laser carriage gantry wheels (#3 in the pictures). I personally ran these wheel for 5 months on my Glowforge.
Replacements from Glowforge are hard to get a hold of, so these are great to have handy in a pinch while you wait for stock replacements.
3D printed out of hardy PETG, they are made to fit the carriage gantry wheels with the 12mm bearing. Either reuse your factory bearing, or we sell replacements installed! Bearings are a tight fit so that they do not wiggle out once pressed in and will take a bit of force to press in.
• Choose from a pack of 2 wheels. (Select with or without bearings)
• Or use the drop down to purchase multiple packs at a discount
** Bearing Install Instructions **
First, have the old bearing out of your old wheel. Then put the new bearing on a flat surface and set the wheel on top, align the bearing with the hole. The bearing is a tight fit, so it needs to go in straight (any angle will cause issues). Pushed, slowly, straight down.
Adjusted it from either side until it was pressed in the middle of the wheel. About 1.5mm of space will be from the top of the bearing to the top of the wheel.
** Disclaimer **
Please follow the above install instructions. The bearing are a TIGHT fit, and if not installed correct the wheel could break.
The bearings are friction fit to account for the heating and cooling of the wheel. They are a tight fit so the bearing does not get skewed when the wheel heats up and expands slightly (the wheel would then cool down leaving the bearing skewed and you’d have a wobbly wheel).
Due to the nature of 3D printed items, there may be slight imperfections that will not affect the laser cutting
