Paracord spool for 50 ft +/- of paracord. Holes are used to anchor the cord to the winder so when packed it doesn't come unwound. Can also be used to fasten objects to the winder to create a a survival tool kit. 

This is a remix of @IvoSlanina's  Rope Winder model.

I printed this using ABS and PETG on an Bambu X1 Carbon using the following settings:

• 0.6mm nozzle
• 100% infill
• Sport Mode

A couple of other models are featured in the photos, a Simple Paracord Tensioner and, Paracord Zipper Pull.
