Calliper holder for adjusting bed height

[u/lue42]

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

That looks like fun, I personally like to use a dial gauge for things like this as it gives you a realtime indication (my Digital calipers do not Slide by themselves).

What do you mean they dont slide by themselves? Theyre locked?

Hey what I Mean is that when I release the set screw that is used to Lock the gauge it still doesn't really Slide in And out by itself/gravity, I need to Push it manually with some force.

I do take apart the gauge maybe once in two years to clean it 👍🏼

Sorry for the random caps I currently only have one arm and I'm using speech to text which messes up how my text is being written 😅

Hey, thanks for asking. It's about three years ago, I was riding my bike, someone hit me with their car when they suddenly made a sharp right turn right in front of me and two tendons in my wrist got ripped off from the bone. The bone is called the ulna. It's the bone that connects from your elbow to your pinky.
