mini Wind-Up Boat Dual Drive - screwless - full 3d printed

I love these little boats!

This time with dual drive!
Now the boat goes much further, lasts longer and, above all, it finaly goes straight ahead!
The drive spiral is made of PETG this time. This works much better than PLA.

All parts are printed on my original Prusa i3 MK3s with Fiberlogy Vertigo PLA and Fiberlogy transluzent orange PETG.

The shell is designed to be printed in vase-mode ;)
Total print time less than 10h!

The full STL includes a less powerfull version of the spiral so be sure you print the spiral-xp version!

YOU HAVE TO CLEAN SOME HOLES OF YOUR GEARS!!!

You need a rim or a drill for
5mm
6mm
8mm

Notes:

finetune your extrusion multiplier! This test works fine: https://www.thingiverse.com/thing:1622868

Be sure you got no elephant foot! Use elephant foot compensation! Something around 0.15mm works great for me.

For the gears: play around with the extrusion width. 0.4mm at 3 perimeters works great for me.

Print the 2 shafts with brim!
