I needed a way to store my flat patch lead and neatly store it in my backpack to reduce tangling.

Nothing I could find worked the way I wanted it to, especially for flat patch leads.
I also wanted something easy to operate and not too bulky or heavy.

Eventually after trying a few, the Cable Storage Reel from GuyIAm was the closest one but it wasn't sized well for my cable and the walls were quite thin and started to break. Then I designed this version, which is working much better on site.

Printed out of PETG for better flexibility and resilience, PLA will probably be fine too.
