This component is part of the [Open-source optics project](http://www.appropedia.org/Open_source_optics), whose goal is to radically reduce the cost of scientific optical hardware: by the [Michigan Tech's Open Sustainability Technology Research Group]( mse.mtu.edu/MOST).

We made it for just standard smooth rod - the same used for RepRaps.
Your schlieren setup - using angle extrusion for an optical rail - is brilliant - I will look forward to seeing them up. Most of the standard physics optics college experiments use only a rail that can go for over $100/ft that a
lone could make systems affordable for most schools and push the switch.
For our setup we are building a PL and a QE for solar cell research - so we are going to need everything to be moveable in x and y - shoudl have the magnetic base plans up next week along with the automated filter wheel.
a couple of groups job on the wagon we should have an ultra-low cost open optics setup ready for anyone that needs it by the time school starts.
Nice design! The vertical rod is optical post, or are you planning on precision rod or something from McMaster?
I have been trying to do something similar, using aluminum angle from the home store as an optical rail. I got distracted this summer, and haven't gotten my (not so awesome) designs up on Thingiverse yet, but I am happy to see someone else thinking on these lines.
In the meantime, if you are inte
rested, you can see some of the mounts I printed in this video (http://youtu.be/fgCn6SYeVT0) describing a schlieren photography rig I set up. You can see better quality schlieren video here (http://youtu.be/bGskL2wdQ54).
