Fully printable set of 4" dial calipers. It has 9 separate moving parts and can be printed as one complete assembly or in pieces. The smallest gaps between separate pieces are about 0.010", so if you want to print this as one complete assembly make sure your printer can support this and can print modeling and support material together. Alternatively, you can scale up the design to increase the gap size or print out the pieces and assemble it by hand. I haven't tried assembling this from the separate pieces but it should go together with a little hand work and super glue.
If you find that there is too much friction to move the calipers try applying a plastic-safe grease to the gear teeth and gear faces. I used a little Crisco cooking grease for this and it worked very well.
Calipers include inside & outside jaws, depth gauge, adjustable & locking dial, and thumb wheel.
I actually found the precision in measurement to be surprisingly accurate. With a little care you can get correct measurements to within +/-0.0025".
This was printed on an Objet Eden Printer.
Scale STLs to 78.74% of original size to convert to metric.
