Drill Powered Outboard (Work in Progress)

https://youtu.be/Ix5F3YQOyLg

Assembly requirements:

Print

  • 1x Propeller of your choice
    • There is an edgeless propeller (prefix WIP), but it is an untested work in progress and requires two M10 nuts and print pauses. It's also quite large at the moment.
  • 1x Handle
  • 1x Bearing Support
  • 2x Bearing Spacer
  • 2x Bearing Cap

Buy:

  • 1x M10 Threaded Rod (I use 1000mm)
  • 7x M10 Nuts
  • 2x 26x10x8 Bearings

Printed out of ASA using a Flashforge Creator 3 V2 with the following settings:

  • Layer height: 0.2mm
  • Infill: 25% Gyroid/3D
  • 5 Outer Layers
  • 5 Top/Bottom Layers
  • 100mm/s
  • No supports (depending on your printer, you may prefer to support the propeller blades)
  • No bed adhesion
  • Propeller requires pause at 29 or 19mm (aggressive or mild, layer 145 or 94 at 0.2mm) in order to insert the nut.
  • I print the propeller in one, and the handle assembly in another. But it's up to you!

The handle assembly acts as a frame to hold the bearings, bearing caps and spacers. The propeller has an embedded nut. Everything is tightened, and then locknuts placed across the primary nuts. The bearings can be tight, so you may need to scrape a little off of the edge of the hole. You can use the nuts and bearing caps to press them in.

There is also a bracket to slide onto the handle for support on the back of the boat. This is currently untested.
