Seeing things running through MY head.

In my quest to design a fully 3D printable Ghsotbusters' Proton Pack, I've had to make the part known as the 'Synch Generator'.

This is a large part, and it's the biggest thing I've ever made, weighing in at about 770g.

It's made of 6 paired copies, plus two other pairs, and is designed to be bolted together with M4 bolts. I printed it all in PLA to avoid ABS warping. Both my printers are in heated chambers, but even that struggles to prevent warping on such large parts.
