HENRY THE HELICOPTER is a one piece print test that you can use to test and calibrate your printer.
Download the single STL file [ HENRY.stl ] to print in one go. When completed you can remove the support structure and the rotor blades will spin freely.
Yes it prints upside down!
30/3/19 - Added HENRY_NO_SUPRT.stl for anyone that wants to print with their own support. Plus various files to enable customisation. Please feel free to have a play!
I use a wall thickness of 2mm with an infill of 25% and get good results from these small prints.
