firstly, to create this i had to grapple with a very uncooperative, crash-prone inventor. i apologise if extra details and aspects are missing, but i felt i had to persevee and provide some form of my idea. I have created an effective solution to a simple problem in an easy to print spool holder, which will hold both small and large makerbot spools. The file can be changed to have any word on the tab, my display picture shows "PLA" written. These hooks should be fast to print, and easy to use, and would hang like a coathanger. Enjoy :)
