These FSR bed mounts maximize the printable volume, and they look nice too.
Modified from iksbob's heated bed brackets to fit FSRs, while also fitting above the power supply mount. Removed the tabs above the glass for easier bed installation and removal. For 170mm diameter glass build plates.
It is not as rigid as some other FSR bed mounts, but I am using a variation on the Trinket Auto-Adjusting FSR Endstop Detector (see http://goo.gl/lLnAQk), so very little pressure is required to trigger. Also, you may want to add some tabs to keep the glass from popping up if your FSR's require more pressure to trigger.
Printed three pieces at 33.3% infill (more infill probably wouldn't hurt if you want), 0.2mm layer height with support. Attached using M3x8 cap screws and nuts in the extrusion. You probably want to use a super grippy material or double-sided tape between the FSRs and the bed to ensure the bed stays put.
