This is a clipstick which is to be used with a telescopic rod from the company Leifheit like this one. But I also included the step file, so you can modify it to use with whatever flor wiper rod you got lying around.

The uploaded version I did not print yet. I reinforced the back of the clipstick because the print in the picture broke right in the reinforced spot due to the poor layer adhesion of my cf-petg print.

For Supports: I print the clipstick standing upright (like in the picture) and only use  support on the bottom ring so it has a nice connection to the print bed. For my printer atleast every other overhang was possible without support.

Update:

• The last version (v18) was a little bit too small both for the fit on the stick as well as the fit for the expresses
• The last version broke in the small section so I reinforced that part
• The holder of the express is a little bit tilted (15º) it is easier to get the express in the hook in the wall
• I printed it in both PETG as well as PLA both work fine. The last time I printed in in Ninjatek Armadillo and this worked the best due to the increased flexibility.
• And as a small last note: Commercial use is now allowed, but I would appreciate it if you would give me a heads up first ;)
