Board Holder

I needed something height adjustable to put my second PC-Monitor on, so i made this fast. It isn't perfect, but it works for my Monitor (weights about 1.9 KG) so i figured, that maybe someone can made use of it.

The board i used is about 0.85 cm thick and 13.5 cm wide. It should also work with slightly thicker and wider boards, (I think the maximum thickness can be around 0.9 mm and the maximum width around 14 cm)
If you use a thinner board, just put paper or something like that in possible spaces.

I printed the main part together with those pins, that are used to adjust the height, and it worked for me. It may be difficult to lose them after printing, so i made a test piece and one main part without pins. I also made extra pins, that can be added afterwards, but you can also use something more stable like a nail or a screw.
