Humminbird Transom mount

My boat has a cheap PiranaMAX 150 LCD depth sounder by Humminbird. A few months ago on a bad launch during rough weather, the transducer mount struck the concrete boat ramp. Needless to say, it broke away from the boat. I tried gluing it back together, with limited success. Since then, I have purchased my 3D printer and whilst out fishing a few days ago watching it flail around behind the boat, the genius penny dropped to make my own! Actually, no it didn't. The first thing was to spend 3 hours searching for a 3D model to print, alas there were none. 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 "Prototype" mount to see how it fits. I say prototype, because I forgot to add the nut recesses and found a few hollow areas whilst printing. This newer version should work just fine. It will also be a lot stronger than the original Hum
