Under desk large tissue holder

This is a remix of a smaller tissue box holder. I liked it's simple and rugged design, but it did not fit my needs. Through some measurement and verification this now fits the 120 count 3-ply tissue holder for the larger size 8.2x8.4 in or 20.8x21.3 in ‘Clean’ex brand box. The actual box dimensions are roughly 12cm wide, 8cm tall and 22.5cm long. Includes partially countersunk screw holes.
