Secret Transformer Box - Autobot Logo

This a remix of 3DPRINTINGWORLD's awesome Butterfly puzzle box.

All I did was remove the butterflies and added an Autobot decal to the top.

This is the box printed in Rupunzel Silver & Vertigo Galaxy PLA's from Filamentum (with Filamentum CPE/PETG Spring and Key).

The spring was quite tough to get right with PETG. I think printing it with a big nozzle (0.8 or so) would be very beneficial. I cut the spring down a little and it worked fine. CPE certainly has a lot of spring to it.
