I currently have 3 monitors hanging with this mount, The largest of which is a 28" monitor ( using only the wall and monitor bracket, no arm ), The strongest way I have found to print this is with pla plastic using makerware's high quality settings ( 3 shells 15% fill, @ 230c ) It is much stronger then the abs prints of the same device, I have had a 23" monitor mount break under abs, but with the pla it is holding up the 28" just fine (although I am going to be designing an additional bracket just to be on the safe side )

I also created a few remixes, one is a pin that can be used instead of the 8mm bolt, and the other is an angle bracket for if you want to rotate it a little bit

If you post the original design files, I'll run FEA (finite element analysis, used for analyzing stresses in a part) on it and see what loads you could expect to put on it without issues

I cant get the wall.stl to download... it just goes to a page of code... any thoughts?

Works nice, I have 2 monitors ( a 22" and a 19" ) on this, the only thing different I had to do was rotate teh wall.stl on its side, so the layers where not parrallel with the monitor, ( also I used 20mm x 4mm screws, the standard 10mm x 4mm where not long enought )

Currently testing my one of these I printed all looks okay with 4.5kg on it (10lbs in old money!).

My monitors weigh in at about 3.1kg so shouldn't be an issue (I hope!)

Nice, should be handy.

Any idea how much your monitor weighs? If not what size?

You have a lot of force parallel to the direction the layers were built up. If you end up having problems with this, (the layers splitting) try printing it on another axis with support material.
