Size Jig

When creating objects, I often found I needed to reprint as the plastic printed was not exactly the correct size.

I have created a set of size jigs for PLA and ABS plastic in 0.25 mm increments . These are both pins and holes and can be attached to a key ring.
Holes are handy for selecting screw sizes, and the pins are handy for selecting the correct size if you need a pin to fit in a hole.

I used a "Paint Marker" with the point on its side to mark the increments over the embedded sizes.
