Monitor Shelf | Clip-on

Made for a colleague who wanted a little shelf on his monitor, to keep pens and other small bits.

It clips on the front lip of the monitor and holds itself in place.

Here is the OnShape link so you can make it fit your monitor.
If you prefer other software, the step file is included.

It can be printed without supports and stronger when vertical, however this takes significantly longer time.
Otherwise it can be printed flat with a few Tree - Organic supports. 
(See pictures for both variants).
