I had some issues with the original design beeing a little to loose and angled to much so i created a new version which has quite a tight fit (Be sure your printer is calibrated well) and the screen is mounted completely vertical without tilt.

Printed in PLA-HS Textured Gray from Anycubic
0.2mm layer height on its side without support
3 walls, infill 15% but I think it's negligible.

Parts needed:
2 x M4x10mm screw
2 x M4 Nut
