Mast bottom cap fastener pin diameter?

I 3D printed a replacement bottom cap for the Sunfish mast however, the fasteners are missing.
Tried measuring with a few drill bits and don't have the exact size. The hole seems to be near 0.07" (1.75mm).
Is there a standard diameter for the fastener pin?

I'll probably try with galvanized brads or maybe a dab of 3M 4200.

Two ways to go...maybe three ;).



I just glued the base cap with Shoo-Goo.

I don't have a micrometer, but I do have a new mast base cap and a set of drill bits. My eye says that the pins are the same diameter as my 5/64 inch drill bit (on the left), and smaller than my 3/32 drill bit (on the right).

If the drill bits came from a drill "index" (with known dimensions) insert the unknown pin into the hole that the suspect drill bit came from.
The info in your message signature tipped me off to the solution! Pulled out my box of pop rivets and found the 1/8" mandrel to fit perfectly.
This is actually a mast to a Minifish.
