Monitor shelf - perch - holder

EDIT1: Fixed an error that I missed originally. Also made the rear brim smaller by default as the original was unnecessarily very long.

EDIT2: Option for "Lego(tm)" top added!
Also added "shelf_thickness" to allow for thicker shelf compared to overall wall thickness of other parts.

EDIT3: Customizer seems to not work anymore online. You will have to open install OpenSCAD and edit the file manually...it's easy!

EDIT4: Customizer FIXED! Click "Open in CUSTOMIZER" above to adjust for your monitor. Or go here - https://www.thingiverse.com/apps/customizer/run?thing_id=2698416


EDIT5: Added another parameter to move the center of the shelf for thin monitors. move_mount_distance
