Parametric OpenSCAD Paper Fasteners

These are a 3D printed alternative to brass paper fasteners. Use OpenScad to customise the gap to get the perfect spacing for whichever craft you're doing. 

Here are some ideas:
Toy clock
Skeleton
Phonics fans
Pinwheels
shadow play puppets

They need a little bit of force to click together. Try lightly tapping with a hammer, using a vice or clamps. Otherwise try adjusting the clearance in OpenSCAD.
