Fusebox-Hypercube Hybrid for FLSUN cube hardware

I've posted these parts since I know the adapter works, I linked the other parts that I used, will give a shopping list of the parts used (only about 30-50 bucks for bearings from amazon)
list of what's required:
3m GT2 belt (getting 5m wouldn't hurt)
16T GT2 idlers (8 total, preferably 6 toothed/2smooth)
M3 screws and (locking)nuts, you probably have extra, but I used ~10 additional 25mm long bolts for holding the idlers

Good things to also get:
