This is an adaption inspired by:

I'm not labeling as a remix because I didn't use their models, but rather used theirs as inspiration for my own bottom up design. Not sure if this is a correct label, but there is the logic. 

The different form factor from their design is to center the chuck (ArtyMaster 2 inch Mini 3-Jaw Self-center woodworking chuck. M18X1.5mm Thread and 0.4 inch connector Mini lathe Chuck) in the center of the securing points using the anchor 1 or 2 points so I can use the anchor 1 or 2 origin as my datum. In my head this works better for me to set up my projects. I am using the STL to make cuts on an aluminum block which will eventually become the final design, but in the interim I can use it build the metal fixture and other projects.

For the PLA version posted here, I printed the model with threads and then used the ArtyMaster 2 as a die (as in tap and die) to make the printed threads match the chuck. Treat it like any other die. Slowly thread a bit, back off then advance incrementally. Significant hand torque is required, but eventually it nests quite nicely on the model.

Finally the moniker "Grippy" is a nod to a Megan E. O'Keefe character from The Protectorate series. Because Grippy is awesome, as are the books.
