Description
These Side-Power bow thruster units are built for marine environments, but the exposed control heads and connectors can still suffer from prolonged water exposure and UV damage. Surprisingly, they don’t come with a dedicated weather cover — so I designed one.
The cover is easy to 3D print and installs in seconds. It includes a small hole for attaching a lanyard, so you won’t lose it overboard.
If the fit isn’t perfectly snug on your unit, simply adjust the scaling slightly in your slicer settings to dial it in.
Disclaimer
My models are always tested on my own boat or on others. We are currently cruising to the Caribbean and you can therefor assume that we load up the part properly. It is however your own responsibility to use these parts when heading out to sea. Use common sense and print spares if you are not able to print onboard. Especially on longer passages.
