Nextbase 522GW Dashcam Click&Go PRO GPS Mount 3M Base

My Nextbase 522GW came with two adapters for attaching to the window, a suction cup and a flat plastic base for use with a small piece of 3M VHB. I had only used the suction cup for years and now that I want to permanently attach it with the 3M tape I couldn't find the backing plate anywhere. So, I sketched up a quick model in Fustion360 and after a few prototypes, came up with this, which seems to get the job done. I got rid of the “clicky bit” in the middle, you can just see a rectangular cutout in its place, because it was an absolute nightmare to print with or without supports if I used PETG, which is ideally what I wanted for its heat resistance. This seems to lock-in quite nicely though, even without this piece, so it will stay a cutout :)

In the hopes that someone else will find this model useful, I'm publishing it here along with the original fusion file, so feel free to make modifications to it however you see fit.

I recommend to use a layer height of .20mm (I had pretty bad stringing below that)

I've just used the default preset for PrusaSlicer: 0.20mm STRUCTURAL - Prusament PETG, printed on my mk4.
