AVR Component Tester, customizable, schematics

This is an enclosure for a component tester of my design.You can by a tester like this for $5 (without enclosure), but why buy when you can build one yourself for $100? :-)For software, parts list and build instructions of the electronics, go to https://github.com/jonsag/avrComponentTester.To customize, download all scad files and edit casing.scad.You will also need the (incredible) OpenSCAD library at https://github.com/nophead/NopSCADlib and adapt the paths to this library in the other two scad files.To get a knob for the rotary encoder, you can design one with this thing: https://www.thingiverse.com/thing:4712953.
