String Biplane: No Supportsby
A String Biplane model with spinning propellor and wheels
Print the Biplane file at 0.3mm layer height and if using Bambu Studio make sure your wall generator is set to Arachne.
All parts are printed without supports
I found a brim allowed me to print the front file at a faster speed.
To assemble place the 'propellor back' into the 'engine', push the propellor through and screw in place, then screw the engine and propellor into the front of the Biplane.
My Biplane is printed in Geeetech Bronze Rainbow filament which you can find here: https://amzn.to/3KKlZrU
I also have a version with hanging rings attached which you can find here: https://than.gs/m/923028
