Hovercraft

thingiverse

The complete hovercraft file won't work, but it's designed to give you an idea of what the final product looks like and how its parts fit together. Working hovercraft with two thrust props are designed to be printed on a 220 x 220 x 240 mm platform. No smaller or larger parts will fit. The longest print time is about ten hours, but some parts need to be printed more than once. These are obvious. Propellers aren't included, but I recommend using three or four-bladed ones with a 10/9.5 cm diameter. I've designed propellers: four blades at https://www.thingiverse.com/thing:2829558 and eight blades at https://www.thingiverse.com/thing:2829551. However, I advise against printing these because 3D printed props tend to disintegrate or become very heavy. Use the reworked skirt frame files. Use thrust ducts for lift ducts as they're the same. Make the skirt from a bin bag by gluing it inside the outside rim and the next ring in, ensuring it's fairly loose. Three motors and one 9-gram servo are required, along with possibly more wire. All electronics are designed to fit into the front part of the craft. You may need to adjust the center of weight by moving some components around. This is untested, so I'll update when tested. I'm currently printing it. The complete hovercraft file won't work and is just there for reference purposes. Update 1: I've added a roof for the cabin at the front, featuring an adjustable FPV camera mount. You'll need to secure the slider and camera with blue tack or something similar so they don't come off. Unfortunately, I'm unable to upload the slider yet, but please wait while I resolve this issue. The updated fan housing can be used instead of the standard one. It has larger screw holes, a lower motor cowling, and a break in the cowling for motor wires to exit. Update 2: I've made the body thinner to allow air to circulate under the skirt and make it lighter. I've also split the body into four parts to reduce print time and accommodate smaller printers. Update 3: When printing, I noticed a design defect where one of the slots on one side of the body didn't print. This has now been fixed. The issue was specific to the updated body sections.
