Needing a way to use my new pen and tablet without pushing my keyboard around all the time, I decided to create an accessory clamp that can be used and built upon to mount random crap to a desk or table.
I modified the Monster Mouth Headphone Holder by philbarrenger. I use his mount both at work and the office, and thought it would be the best place to start.
Uses a ~29-30mm rod and a thumb screw to mount any random crap you need to be clamped to the edge of a desk. The thumb screw rod design also allows you to add adjustable height to your accessory.
This is just the clamp, a platform on which you can create random crap for. use it well. An example of an accessory (the easel/stand I designed for it) can be found here:
