Boat built-in horn cover

thingiverse

This is a replacement cover for a boat/marine horn. Dimensions: 13 x 7 x 0.7cm (screwholes 10cm apart). I've designed the cover in OnShape and sliced it in Cura before printing it with a 100% infill for strength and minimal warping. TIP: You can make a cut out of a thin silicon baking mat to use as a seal between your boat and the cover. And you can use a piece of thin synthetic cloth between the cover slats and the seal. This way you reduce splash water from seeping through the opening of the cover.
