Iris V2 Keypad hardware issue. 3D print model? STL file needed

So Alex Sari is selling Iris V2 keypads, I bought 2 of them and 1 came without the plastic wall mount.

Now my local public library has a maker space and I can print out small objects like the mount.

Now before I dive head first into Sketchup to create the model and export it to STL so I can do the print, I have to ask. Does anyone here have an STL file they have already done they are willing to share to be able to print out this mount?

The velcro attachment I am currently using pushes the keypad further away from the wall than I like...
