thingiverse
The LED diameter is 31mm, and each LED costs approximately €3.20 from Amazon (http://www.amazon.de/gp/product/B00BEU22PQ/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1). Suitable for 12V AC/DC, these LEDs are used in the first revision of the project, which had minor issues like small holes for Velcro and missing fixing and switch holes. However, the second revision addresses these problems (uploaded file) and has not been tested yet. There are two cases available to accommodate the switch hole. The switch is a mini metal type with one pole and a closing electrode (http://www.amazon.de/Mini-Drucktaster-metall-1-polig-Schlie%C3%9Fer-Elektronik/dp/B000OH7W0U/ref=sr_1_3?ie=UTF8&qid=1386512190&sr=8-3&keywords=mini+schlie%C3%9Fer). For fixing, use 10mm wide Velcro. The design was created in FreeCAD and printed with ABS on a Mendel Prusa i2 3D printer.
