The plastic timing belt retainer* on the right side of the gantry fell off when I was cleaning and troubleshooting Glowbert my Glowforge. Upon inspection I discovered that the retainer is cracked. I reinstalled the part after the cleaning+maintenance procedure I was performing. The part is still functioning in the Glowforge, but I don’t expect it to last very long.
Is this a commodity part? If so, what is the part model number so I can find a replacement? If not, am I able to get a replacement from Glowforge?
This part has never been removed or fallen off before. Given the lack of wear on the rest of my machine, it seems odd that this part should fail in this way. Have you seen this before?
*Apparently sometimes called a toothless idler pulley or (if it’s tapered) a tapered bushing.
