NFC Door Lock Housing

thingiverse

Decided to build this awesome Arduino project based on the design from http://www.thingiverse.com/thing:735525 by Qtechknow. Realized I needed a modified design to fit my KwikSet deadbolt, so decided to create an all-new housing from scratch for a sleeker look. The original design exposes the servo and uses hot glue for mounting it, whereas mine gives it a much neater finish. Found the Instructable on the 735525 page, with additional photos that fill in the blanks for assembling my pieces together. Might update this project with a port for micro-USB power connectors to charge lipo batteries but feel free to add a hole or slot wherever needed. Printed with ABS at .3 layer height; might look nicer with .2 layers, 50% infill mostly, thick perimeters for walls, and tweak settings for your printer. The motor-cap requires support, holes on sides secure with 4mm bolts/screws for tightness, and a hole in the cap's top/bottom runs the servo power cable. Trimming the mounting tabs from the body kept the motor cap as compact as possible. With Qduino mini still not widely available, tips on hooking up a Sparkfun 3.3v pro micro to an adafruit NFC shield using a lipo battery for power are greatly appreciated due to limited electronics knowledge. Big thanks again to Qtechknow for the excellent project and Instructable!
