Summary

A Kossel mount for autolevel FSR's, suitable for Misumi 2020 extrusions (M5 screws). Also: glassclips and a handy part for mounting an FSR connector, all with M5 screws.

Instructions

Those of us with Kossel 2020 printers built from Musimi extrusions like to use parts and accessories with M5 screws and holes, instead of the OpenBeam parts that come with M3 screws and holes. I have adapted eddieparkers customizable FSR mount (http://www.thingiverse.com/thing:365760) for M5 screws and a Kossel with a 6cm high base. I'm using 3M bumpon pads (19mm) under my glassplate. Bumpons provide the perfect combination of flexibility and incompressibility, but they are a bit thick (4mm). Therefore I've made the FSR receptacle in these mounts a bit deeper.

Also, I've designed some glassclips with M5 excentric holes to use with a 18cm glass plate.

Finally, there's a handy mountable part you can use for connecting your FSRs. It houses a 4x2 strip of motherboard pins, as show in the picture. Solder these pins four by four at the bottom, so you can use the strip to connect the three FSRs in parallel. Use the fourth pair of pins to connect the FSRs to your RAMPS. Mount the part with M5 screws to your Kossel frame.
