Fits ¾ inch outer diameter dowels and pipes. I used wooden dowels. Note that the precision and tolerances of standard dowels is not very tight but the variety I had all fit, some easier than others.
Example of ¾ inch dowel for sale.
The hanger and both variations of the clamps has been updated to ¾ inch. You will still need the original wall cleat or other method to mount them to the wall.
Use the same print profile as the original. This can be done in prusa slicer via “File → import → select original model → import config only”
