A customizable .scad file for generating a rack with round or square holes. This was designed with cuvettes and vials in mind, but should be useful for any number of things.Update: Now fully customizable, simpler, all in one .scad code. (If you are looking for the customizable cuvette and vial racks I used to have up, this is the place.) For a custom rack: Open in customizer! For a 5x2 rack of 1cm path-length cuvettes: You can probably just download the example .stl (cuvrack_5x2.stl) file and print that. I've also included a .stl file (vialrack_1dram_5x5.stl) for a 5x5 grid of 1 dram vials (I think it should work, I haven't actually tried one.) Reminder: Be mindful of how resistant your rack is to the contents of the cuvettes/vials. (Depending on what you make the rack out of, and what you have stored in the cuvettes/vials.) Shameless plug: 'cuvrack_5x2.stl' fits nicely with this thing: http://www.thingiverse.com/thing:24027
