Assembly

Prepare the paracord ends with melting to keep them from fraying, and to ease threading through the end cap eyes. Keep the melted part as small as possible!

Threading the loop end through the holes makes assembly easier. Using an iron wire also helps.

Production

Use a 0.25mm nozzle, the parts are tiny! Print quality will be better if you print several pairs - layer cooling time is too short if you only print one. 
Tested with ABS and PETG.
