Bracket for ADXL345 accelerometer to fit on Tronxy X5sa

thingiverse

This is a bracket to fit an ADXL345 accelerometer PCB onto the Tronxy X5sa standard steel backplate. This is intended for temporary fitment, measuring resonances for Klipper input shaping. The PCB is correctly aligned with the X, Y, and Z axes - though it is typically used only for measuring X and Y as these are the axes that move quickly. The bracket is then removed before using the Tronxy to print. The two M4 bolts securing the cable chain are replaced with longer versions, then two nuts are fitted to hold this bracket in place. Two small screws (self-tapping type about M2.5) are used to hold the accelerometer PCB in place. There is space allowed for the solder joints under the wiring. Access to the nuts is rather tight but I have a ground-down 7mm socket that is ideal at times like this. I recommend doing this to some of your less-expensive sockets next time you're near a bench grinder - they are so much more useful when slimmed down a bit! I guess there is a chance this bracket will fit somewhere on another type of printer - best of luck with that one - I have used Designspark Mechanical to design the bracket, which is my favourite software for this type of designing. Thanks for checking out my thing :)
