wind-up Bathtub Toy Boat V6 - Badewannen Boot zum Aufziehen

Thanks to Mike for his great work! Based on his model I redesigned most parts to improve it further, I hope you like it.

Improved features:

- Propeller driveshaft of the original was prone to snapping off. Now it is a 2-piece design, where you can print the propeller side in horizontal direction, which is much stronger. You can also print it in TPU which makes it virtually unbreakable

- Gearbox assembly redesigned - the gearing is the same but every other part improved: much lighter, less prone to water adhesion, 5 fewer bolts, 6 fewer nuts, same power.

- Main hull is smaller -> less material, less print time; less buoyance needed due to weight reduction

- Added an attachment point for a rope on the bow, if you want to play in a river

- when sitting on a desk, the boat is no longer resting its weight on the propeller

You will still need: 5x M3x6 (or M3x8), 1x M3x20, 1x M3x30, 1x M3x40, 3x M3 nyloc nuts, a drop of superglue to attach the "Wellenlager" to the gearbox assembly.

Printed in PLA (the hexagonal driveshaft can be printed in TPU, but PLA works as well).

I recommend to print the "Kegelrad" parts as well as the "Schraube" with a reduced layer height. I strongly recommend to get yourself a 3mm Reamer (Reibahle). It's just 3€ here and will reduce the friction in the gears noticeably.
