Description

The ITCHINATOR

This back scratcher started out as a little CAD learning exercise, something to practice modelling threaded parts and multiple components. But after printing it, I realized it actually works really well… and even my cat loves it (turns out it doubles as a pretty great pet scratcher too).

Version 2, The ITCHINATOR MAX, is available now. It has been redesigned to be more robust, and includes a MAX Scratching power head attachment. Separate Print Profiles are available for each different Scratching Head.

The ITCHINATOR's key features:

Three part design: Two 200mm segments and a scratching head, all threaded for an easy and strong assembly.
Bambu Lab Friendly: Sized and oriented to print on all BBL printers.
No Supports: The extension rod has a thin flat surface on which it prints on, eliminating any need for supports.
High Strength: As the components are printed horizontally, the layer lines run parallel to the force applied when scratching.
Ergonomic Handle: The finger grooves are nice and deep, and perfectly spaced (for my hand, anyway).
Effective Scratching Head: Just the right width for a balance of itchy area covered and PSI.
Not Just a Back Scratcher: The extension rod has a rough knurled texture, which is great for scratching other body parts.

There are several print profiles, were you can find all components on a single plate, and each component on separate plates.

There are also two different head options - sharp and not-so-sharp.

If you'd prefer not to have “ITCHINATOR” text embedded on the head, there is a separate plate for no-text head component.

The model photographed was printed with PLA and 0.20mm layer height on a P1S. In order for the handle's finger grooves to be oriented as intended (180 opposite of the scratching teeth), you will likely have to screw all parts quite tightly together. This does not damage the threads, and the more it is assembled/disassembled, it becomes easier to do so.

Please feel free to like and/or leave a comment - feedback is much appreciated.
