Update: 

I added some additional sizes for this toggle button. 

Four sizes are now available. They are: 36mm, 42mm, 48mm (the original), and 54mm. 

This is for the length. The holes in each (for paracord or elastic) are all about the same. In other words, the holes did not shrink when the size of the button was scaled down. 

There is a separate print profile for each size. 

**********

This is a simple toggle button for paracord or elastic. 

It is about 48 mm long and 16 mm wide. 

It uses about 6 grams of filament, and prints in about 16 minutes. 

The print profile includes adaptive layer height, so the curves on top (especially) are smoother. 

I modified Binominem's original button by flattening the bottom (so it prints without supports), enlarging the holes to accommodate paracord or elastic, and adding an inset curve to the button holes. It is also scaled down a bit.
