visle's Scaper Hook didn't fit my MK4. I didn't find any that did so I took the opportunity to get more Fusion360 practice and make my own.
As noted in @CrankyKoala_909727’s make, it also fits the newest MK3S+ produced after the release of the MK4.
A little more digging and I found out that the replacement frame (https://www.prusa3d.com/product/printer-frame/) from Prusa3D.com can be used for the MK3, MK3S and MK3S+.
Any feedback would be greatly appreciated!
Note
When assembling, start with the “tool hook” side first. The clip is longer on that side. This will alleviate the greater part stress if trying to start with the “short side.”
Note 2
I've had this mislabeled for months! It should have been marked as a Remix/Variation of @visle's hook. Apologies!
The author remixed this model.
Made the clips deeper to accommodate the deeper frame thickness.
