I needed a new probe for my Chiron running Klipper with a sonic pad, and I found the BIQU Microprobe to be a good value. Used Cal1961's STP file as a base to get the hole spacing right (the microprobe hole spacing is 1mm off from a BL-Touch).

I have made many iterations, but it seems this is the best so far. Works basically perfect with my setup.
I printed it on my ender 3 pro in PETG.
