Humminbird Transom mount

thingiverse

My boat has a budget-friendly PiranaMAX 150 LCD depth sounder made by Humminbird. A few months ago on a bad launch during rough weather, the transducer mount hit the concrete boat ramp and broke away from the boat. I tried gluing it back together with limited success. Since then, I've purchased my 3D printer and while out fishing a few days ago watching it flail around behind the boat, the idea to make my own struck me. Actually, no it didn't. The first thing was to spend three hours searching for a 3D model to print, but there weren't any available. So here we are. Replacement brackets are quite expensive at AUD$51, when I factor in that the initial purchase cost of the entire sounder kit was only AUD$65! I'm currently printing out the new mount to see how it fits. I call it a prototype because I forgot to add the nut recesses and found some hollow areas while printing. This newer version should work just fine. It will also be much stronger than the original Humminbird mount, as I've added an extra support leg where my original one let go. They used really thin hollow plastic, which wasn't ideal. I printed in PLA with a brim because my printer isn't great when the air conditioning system is running and likes to curl everything. I also used supports, but they only filled the main bolt holes, making them unnecessary. Twenty-five percent infill was used, entirely up to you. My 15HP motor won't break that off with water drag. About 10100mm of filament was used. This thing was made badly using Tinkercad.
