Bolt for crossbow pistol

I couldn't find any crossbow pistol bolts. Sold out, everywhere... Corona crisis.
Last-minute preppers... I'm one of them ;-)

INSTRUCTIONS:

Print part A and part B. You also need a nail of 2,75 mm diameter and 55 mm length.

Browse the pictures above to illustrate these instructions.

First take the nail and cut/saw/grind the head off.

Apply some superglue into the nail slots, both parts. Hold the parts with the tip pointing up. Let the glue drip down the shafts a bit, about halfway down. Then insert the nail.
Press the two parts together, making sure they are flush on the other side.
By pressing them down onto a table for instance. Be quick. ;-)

Use a rubber band to bind the end with the nail together.

Now hold it pointing down. Put one or two drops of superglue between the parts from (what is now) the top. Maybe you need to bend the parts apart a bit to let the glue seep down. Then fix the other side with a rubberband as well. Leave to dry for at least half an
