Summary

Fantastic original source file!
Printed first time in 2017 for kids in reduced scale and another printer, now printed again with new one that even with 0.2 layer thickness work perfect!
Most of all parts just assembled with few dots of glue in few of those, and added two parts from the original blaster picture (wire hole for grips bottom frame, two "ejector" - not sure how to call those small parts added :) )

Great final result! again, compliments to the author!!!
