Caliper Holder for Geeetech i3 Pro B

thingiverse

I whipped up a makeshift caliper holder for the extruder carriage of my Geeetech i3 Pro B in no time, and it's been a huge help with bed leveling. The only downside is that the carriage can get a bit wonky, throwing off your measurements left and right. But hey, you can still make do by adjusting the angle after each move - it's not ideal, but it'll get the job done. If you want to get all fancy with it, I've uploaded the Fusion 360 file so you can modify it to suit your needs.
