thanks for this. I modified it and added countersink screw holes to mount on a wall.

I had two failed prints on my A1 before I added supports. The back ends of the handles were too narrow for the height without supports. printed good with supports.

I recommend using PETG with Arachne wall generator for best results.

Printed great and working great. So much better than the previous model that didn't have the PTFE connectors. Super glue doesn't stick to PTFE, so this is the only way to get a reliable connection with the tube. Used these connectors: https://a.co/d/1ApItbs
