Remixed from originally designed by https://www.thingiverse.com/thing:265529
for my Asus Rog 15.6" Laptop. The hole is resized by 28mm thicknesses laptop and I gave 1mm for each side to avoid screcths. So you can fit by 30mm devices in this model.
You can find the small one for small print beds with the same sized hole.
The economic version has now been opened for use.
