This stand fits Laptops up to 17'', one size fits all (tested with 17'' and 14'' devices)
The base does barely fit on the print bed of a i3MK3 - you have to rotate it to the diagonal. Further, add some more perimeters for the bolt and the axles on the support.
Every part is used twice, since you have to print two holders.
