3D model description

Yes, that's right! A caliper for measuring thickness, for example body fat. (I think I do need it)

This is a quick 1 hr print of a functional thickness caliper. Thanks to its 4:1 ratio it can pretty reasonably measure within 0.5mm.

Use 50% or higher infill to get enough support inside - especially where the screw goes.

You will need a small wood screw to hold the 3 pieces together.The screw goes from the top where the washer/nut is. Have enough infill so you will not dislodge the post to which you will screw the screw but even it happens no worries just use bit longer screw so it reach to main body.

It was designed and positioned so no support is needed.

Instead of trying to write on the piece directly (which would impossible to calibrate to zero), I designed a decal that I cut and glued on the piece.

The decal is in PDF in Letter paper size. Make sure when you are printing you don't have any scaling.

Like it and maybe I can win some of the #DAGOMERLIN prizes on Cult3d, yes, it is a bathroom related item - I do have one there for measuring things.

3D printing settings

No support. You need to print the decal on laser printer, but make sure you are printing it in correct size (make sure your printer is set for 100%, not to fit to page)

First assemble the caliper, look at the nose and see if there is any uneven surface from printing. Use sandpaper to make the surfaces of the measuring nose to match tightly. Then print and cut the decal from paper, use spray craft glue (they usually stick to everything) and then position the zero where the needle is.

I printed the caliper at 100% size no scaling, and the decal at 100% as well, but the decal is much bigger than the caliper. How % should I scale it?
