Door Roller for HF Greenhouse

thingiverse

As time passes my Harbor Freight 10' x 12' greenhouse slowly deteriorates. On a windy day roof panels go missing, never to be seen again. There is a 1-800 number that I can call to have replacement panels shipped to my home, the operator and I are old friends by now. Recently the doors stopped sliding open, the plastic rollers have disintegrated and no longer function. My friend at the 1-800 parts line informs me that these aren't a catalog item, that I would need to order an entire section of door frame. But I have a Crealty Ender 3 Pro, an educational Fusion 360 license, and a pair of calipers. I drew a part that mates to the bearings from the old rollers. My greenhouse lives on. (soak the bearings in alcohol then citric acid to dissolve dirt and rust)
