This is a remix from Spirus's design (cc-by @ https://www.thingiverse.com/thing:2978743 -- I would link it properly, but the "paste a link" box is broken at the time of this upload).

I felt the top tab was very flimsy, and resulted in my screen breaking off when I transported my printer during a housing move.

I have re-designed it to make the mounting points sturdy, the screen does not even flex anymore when I'm using it, and it's solid as a rock.

And because I have some other mermaid themed decals on my printer, I decided to add an embossed decal of a cute mermaid to the side of the screen.

There are three sets of files, the Base (this is the base shape with no mermaid decal), the Test-Fit file (this is a flat plate that you can print in half an hour to do a test fit and verify that your screen will fit correctly), and Base with Mermaid Decal -- this is the base with the shown mermaid decal embossed on the side of it as a .5mm indent.

Additionally, I have included the STEP files (not included with the original model, so I had to recreate them in Fusion 360), and an SVG of the embossed mermaid decal (in case you want to use it for something else).

Print with the faceplate down to avoid supports.
