"Das Leben der Vornehmen ist ein langer Sonntag: sie wohnen in schönen Häusern, sie tragen zierliche Kleider, sie haben feiste Gesichter und reden eine eigene Sprache; das Volk aber liegt vor ihnen wie Dünger auf einem Acker." Georg Büchner

Caliper Depth Base / Depth Measuring Bridge for 6" / 150mm Mitutoyo Caliper (and others)

I needed a Depth Measuring Bridge for my Mitutoyo Digimatic Absolute AOS Caliper. (You can read my - german - Review of this Caliper here).
Because I needed it today (when else?), I "desingned" one from scratch. OK. The price was another argument for doing it instead of buying an original Part. :-/

I have also found that the measuring foot can also be used for other calipers, for example from Tesa, Blankenhorn or even these so-called $ 1.50 Things from aliexpress, ebay or Amazon. The caliper must not be wider than 16mm.

So, here ist is, printed with my AnyCubic i3 MEGA, with Filament from Goedis: Black PLA.

I suggest 20% infill, 0.15 mm Height of Layer, 1,06% Flow, 215° Nozzle, 60° Heatbed and 60% Cooling. (I use an Titan Extruder and Sunon Fans, you'll try it with your Standard PLA Settings). Also, I refer to add supports for the recess. See Screenshots.

You'll need a M4x8mm Screw to counter the Caliper in the Measuring Bridge. But do this with feeling and very carefully, because the part could bend and then the measurement accuracy is no longer given. In the worst case, you can also damage the flanks of your calliper!

I suggest also to print the measuring foot upright, that is, the measuring surface printed on the printing bed. This is most likely to give a good surface at the crucial points and a right angle. It should be clear that this part is only as good as your printer is calibrated. For serious purposes, I recommend buying the original.

But for sensitive parts for example, that thing is just right.

I recommend following sets of screws, so you have enough of them for the rest of the Week ;-) : 460 Countersunk Screws and 1080 Cylinder Head Screws.

If you need a left-handed version, just mirror it. But you will know that yourself. ;-)

31.05.:


  • Added Version with Threads on both Sides, so you can use the thing as left- or right handed

  • Added a 10mm higher Version with two more screw holes. So the caliper sits bombproof.
