This is a mild remix of the Cutter for Ultimate Nozzle Wiper to accommodate slightly larger tubing (e.g. 8mm OD).
I found that the “Feelers 3mm ID x 8mm OD High-Strength Silicone Tubing” (amazon.com link) works very well for the Ultimate Nozzle Wiper Prusa XL.
Included are STL files made for 8mm tubing (with 8.5mm and 9mm cutouts - I prefer the 8.5mm which is tighter, but it needs a bit of coercing on occasion to remove bent tubing from the deeper hole).
I am also including the Fusion 360 source, which is based on the original STL. There is a parameter (Solid > Modify > Change Parameters, pick tube_diameter) that is used to drive the diameters of both cutouts.
On the picture, the original cutter with 7mm OD tubing, the 8.5mm version with 8mm OD tubing and the 9mm version with 8mm OD tubing.
The author remixed this model.
Both cutting holes can be made larger.
