Harbor Freight Dial Indicator Holder for Chimera Mount

thingiverse

I had trouble calibrating my first delta printer, an He3d K200. I needed a way to attach a dial indicator, but all I could find were designs meant for single hotends. My machine is dual - the hole patterns are different. I found a mount that looked promising and modified it here to attach onto the effector. Keep in mind you'll have to remove the hot end to use this setup, but it positions the dial indicator close to center. Additionally, you'll need to adjust your z max height so it can lower enough to reach the bed. This design was created for my K200, but should work with any printer that allows mounting above the hotend and can get the bed close enough - most deltas would likely fit the bill, though not necessarily most cartesians.
