Where'd you get your hands on a 3D printer? Also, what's that CAD software you're using that can procedurally create things like that? (Brett) from Anonymous
I used Shapeworks for the printing, one of their material options uses laser sintering which is still too expensive a technology for home use, it cost about $45-50 plus postage though. Made a couple of expensive screwups though, first revision is full of issues, 2nd revision I ordered before I even had R1 in my hands, R3 however when I order it should be about bang on perfect and also a candidate for production if there’s interest.
CAD software is OpenSCAD, it uses a text based language to define geometry but has all of your usual programming tricks modern computer languages have, the slots for instance is a for loop that generates the correct number of slots defined by variables inc. width/clearance/etc. The box with bevelled edges is defined by the filter size plus the wall thickness, which generates the hull of spheres of a set diameter, etc. Only one item is statically defined which is the radius of the cylinder for the finger tab. Everything else is computed from the relationship it has with its neighboring qualities.
It’s pretty neat stuff but very primitive compared to modern CAD software (blocky cylinders, etc.)
