Monitor Riser 100mm - IKEA JÄRPEN

Found some old shelf boards and had to make use of them :)
So I designed two pillars to lift it up. On each side it can be secured with an 4mm screw on the backside.
The IKEA boards dimension are 191x25mm at the opening.
Good tight fit and it raises the monitor or whatever you want 10cm up.s
Needed build volume is 20x10cm
