RC Jet boat experimental pieces

thingiverse

The text appears to be a detailed explanation of modifications made to an RC jet boat, including changes to the design of various parts such as the propeller, rear haul, and top lid. The author also provides recommendations for printing and material selection. Here are some key points from the text: * **Lipo Shorties:** The author mentions using lipo shorties (7.6V 5600mAh) which offer a smaller size and better weight distribution. * **Slicer Output Recommendations:** * Print most parts at 3 perimeters with default infills of 15% Grid pattern. * Honeycomb would be stronger, but it may add to the weight. * PLA or PETG are recommended materials, while ASA is a good choice for its waterproof properties but limited color options. * **Printing and Material Selection:** * The author suggests printing the propeller at 100% infill using Nylon 910 material, which requires full supports to prevent curling. * Supports may be needed for other parts such as the rear haul due to overhangs. * **Design Changes:** * The top lid has been modified with a flattened mating surface and thicker areas around bolt holes to improve sealing. * A flat rubber gasket is used for the deck lid seal, cut from 2MM rubber sheet. * The rear haul design has been changed for better direct drive and includes an 11MM rubber seal for rod bellows. * A cooling system has been integrated into the design, which will require 6mm x 19 fittings. * The rear rudder housing has been thickened up to accommodate 3mm hardware on the new linkage. * The propeller mounting design has been changed to use a special locking collar included with the 4mm shaft. Overall, the author provides detailed explanations of their modifications and recommendations for printing and material selection.
