Ams Side Spool Holder

I created this thing with very limited knowledge I remembered from highschool with blender. This was created for my friend as a quick rough way to hold a loose spool because he has limited space and cannot put anything else on the wall of his rented home. It can definitely be improved upon I just did this in a quick 15 20 mins of brainstorming and It can be vastly be approved such as making the small tip on top wider to fit perfectly with the gap under the ams for a firmer fit. This thing has a small bit on top that can slide into the small gap under the AMS.
