Dial Calipers by angry_monk Nov 20, 2013

Description

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.

I tried printing this on a Replicator Dual using HIPS for support, Makerware high quality, 50% infill. It came out looking great, but some of the small parts broke easily. Should use 90 to 100% infill instead. But some of the parts are also apparently fused. Or possibly, I wasn't able to dissolve away all the support between some close surfaces. Hard to say since both plastics are white. So maybe I will try a different color next time as well.

which printer and what support material are you using? is this dissolvable? thx

when i open the file in makerware i also get the size of 7.43mm x 2.83mm x 0.80mm; which is tiny! I know i can just scale it up, but then I lose the accuracy which is important - what should the dimension be (ideally for the metric units)?

Does this required support material?

I think one version you need to assemble (not requiring support) and the other requires support. I'm going to try it tomorrow and find out.

Excuse me,why my softwares load the STl and it show the caliper's size is 7.43mm x 2.83mm x 0.80mm ?Is it should be use another uint such as inch?

Can't wait to try this!

/sigh...imperial measurement.

Ha, sorry. It was either the unit I use or the unit I sometimes use. But, if you scale the design to 78.74% scale it will read 2mm per revolution. It should still be printable at that scale but I'm not entirely sure because I haven't tried it.
