3d Solutech Masterspool

I bought some of the 3d Solutech Masterspool refills when Amazon had them on sale. The new refills come with 4 tie-wraps instead of 3. Most of the designs I see are for three tie-wraps. I also didn't care for the thread together spools, as I thought a removable side would be more predictable.

This is a first attempt at learning Freecad (v0.19).

I used 8-32 screws to put this together, as that is what I had on hand.
