DIY callipers with imperial and metric vernier
Keeping track of precise measurements and the finest details just became a little easier, thanks to Sean Murphy’s updated vernier callipers on Thingiverse. He has come up with an interesting adaptation of a design that was originally intended to be cut from acrylic and then bolted together.
What did he do differently? Well, aside from tweaking the accuracy a little, Sean also laser cut the measuring device from paper and double-sided taped the two halves together.
“The result is a super thin set of callipers that can be slipped in a binder, folder, or book yet still give accuracy down to a few hundred microns.”
Very handy indeed… and because they are cheap, quick and easy to make, you could keep a set within reach at all times for refined accuracy wherever you happen to need them.
