This is just a simple remix of quint89 Laserbeak - Simple Transforming Cassette
So what's changed?
Size - Scaled up to a bigger size. (Almost life-size)
Body - Removed Transformers emblem. adjusted mount holes for boosters and legs, they now fits just right.
Head/Neck - moved the Decepticon emblem here. Head also articulates to a certain degree for better pose.
Legs - looks more accurate and has an articulated legs which helps grip to an arm(like Megatron/ Soundwave does) or somewhere else - kinda! :P
The pins will need to be adjusted based on printer settings. I also suggest adding brim on these pins as they can be used as support so they won't fall off when assembled.
Thanks for an awesome design BTW ^_^
Print the body.stl as low infill as you can.
It gets a bit heavy when more than 20%
Pins for the neck and legs might need a bit of adjustment. So scale that up to whatever size you need for your printer.
