This is a switchplate for a Mendelx 1.5 based on lcecil's design. It has holes sized to fit these switches (http://www.amazon.com/gp/product/B007B86Z94/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) as well as a hole for a 1k pot for an LED lighting dimmer control circuit I built. If anyone is interested I can provide those files as well.
