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.
