Radius Measuring Toolkit

thingiverse

If like me, you sometimes need to design functional things to fit existing objects, you've probably been faced with taking lots of measurements. When it comes to measuring the radius of an object's curved surface, existing tools have their limitations; sometimes they simply don't fit in the space you need to measure. This toolkit provides a range of curved pieces with radii ranging from 5mm all the way up to 125mm, which you can hold against the outside or the inside of a curved surface in order to determine its radius. The pieces are in 5mm increments so you will need to approximate a surface's radius if it appears to fall somewhere in between two of the pieces. Both the inside and the outside of the pieces' curves are true to their respective radius as printed on each. There is also a tray to hold all of the pieces (I really need to design a lid). These prints are quite big. I have provided the STLs for the complete set of pieces and also the STLs for the odd and even numbers separately. This is so that you can break the print job into two in case the build area of your printer isn't big enough to do it all in one go. If that's the case, you may not be able to build the tray.
