Filament spool holder for the box it came in

You got the box the spool and filament came in but you wish you had a spool holder? Well, here you go. Just cut a hole in the middle of the box and stick these in to hold the spool! Spool tube is 28 mm wide and both pieces together can be up to 90 mm wide. Perfect for Hatchbox filament that each come with their own boxes.

Uses far less filament than those other more total solutions by using the box the filament came in so you can make a bunch of them. The design (or lack of it) allows placement of the feeding box almost anywhere whereas the other design can be very specific with placement.
