i3 Mega Hatchbox Spool Hub

thingiverse

I set out to locate spool hubs specifically designed for the i3 Mega spool holder, which are compatible with Hatchbox filament, but they were nowhere to be found. Undeterred, I took matters into my own hands and created one myself. The result is a snug fit that perfectly accommodates the spool, while the included metal bar seamlessly integrates with the i3 Mega's design, slipping effortlessly through its central axis. What do you think of this DIY solution?
