prusa I3 10mm proximity sensor mount

my hictop printer came with an aluminum bed and 4mm proximity sensor I wanted a glass bed so I designed this it is made to hold this sensor http://www.amazon.com/uxcell%C2%AE-TL-N10ME1-DC6-36V-Proximity-Detection/dp/B00NWFCXFK?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s01

the sensor is double the size and weight of the old one. but has a 10mm reach.

Edit: the stated sensor I received was defective. so maybe choose a different one. also I will update with a 18mm round sensor ad
