This thing is pretty useless. There are far better designs out there that you should be looking at instead.
For .75 inch FSR.
Added openscad file so you can customize it for different beams, screws and FSR.
Mounts on the inside of the openbeam and has a lip to support a circular disk to shield electronics and motors from the heated bed.
There are 4 variables in the scad file that you can modify to fit your needs.
fsr_diam; The diameter of your FSR. Default is .75in (19.1mm) which fits the FSR bought from tridprinting and ultibots
cube_side; Set width/depth of FSR mount
beam_height; Set height of FSR mount. 15 for Openbeam, change to whatever fits your beams.
screw_diameter; Set diameter of the screw used to attach FSR mount to your beam.
I print using the standar kossel mini settings from the reprap wiki;
Layer height = 0.2 to 0.3 mm (around 60% of your nozzle size)
Perimeters = 3
Top/bottom solid layers = 3
Infill density = 50%
