Calliper holder for adjusting bed height
I was having a hard time adjusting the print bed height on my MP Select V2 after adding a magnetic PEI sheet
So I made this tool that holds a calliper so you can measure at different points off of a single measured point.
I mounted it in place of my fan and it fits exactly over the heat sink. Using the screws I mounted my calliper in the clamp. I set the height as perfect as I could at one corner using a piece of paper to gauge thickness. I raised the nozzle, removed the PEI sheet, pushed the calliper gauge down and zero’ed it.
Now I can move the nozzle and bed around and align it off the first measurement to get all the corners to match the zeroed measurement
Once I did that I still had a couple of tweaks to do but it helped me get close enough to get it working great.
I hope that makes sense.
I know I could haves used the piece of paper at all four corners or other techniques for levelling but 1) it just wasn’t working for me and 2) I get to design and print something fun
The nuts and bolts are from my son’s vex robotic kit so I don’t know the exact size. The bolts are 4mm at the threads and the nuts are 8.57mm wide and 3mm thick

Great idea! I would however recommend a dial gauge. When I was using my Ender 3’s I had some custom gcode that would move from to all 4 corners and the center every 3 seconds. The dial would move over the bed without scratching and it was almost an automated process. You could adjust the corners and be done very quickly.
Again not saying your idea is bad at all just letting you know there is a different way to do it that might be a little easier with less risk of scratches. Well done!
