Description
These are pair of vise style mounts for adxl345 accelerometers for klipper input shaper calibration for bed slingers. I found other mounts to be really slow to install with multiple bolts or they are way too bulky to attach to my x gantry.
This version uses single thumb screw and heat set inserts for smooth screw action.
Printed in PETG, 0.2mm layer high, 75% infill, it doesn't need to be super strong since mount is clamped only finger tight to stay in place, vibrations are not that violent.
It is good idea to put something between downside of the bed and screw not to damage heat pad.
BOM:
m3 heat set inserts L 5.7mm : x6
m3x6 bolts : x4
m3x24 bolts : x2
adxl345 accelerometer : x2
cat6 ethernet cable : 0.8m - 1m
raspberry pico : x1

pico case x1: https://www.printables.com/model/226610-raspberry-pi-pico-case
pico case model also contains wiring diagram. I suggest to use ethernet cable for wiring due shielding issues I encountered with using regular jumper wires.
