thingiverse

**Updated with rotating mount** Continuing the collection of Grumman Aluminum Canoe toprail attachments, such as this [rod holder](https://www.thingiverse.com/thing:4835566) and this [fishfinder mount](https://www.thingiverse.com/thing:4851451). This is a side-of-the-canoe mount for a fishfinder transducer. The particular transducer for this is the Garmin GT20-TM and a 7/8 O.D. tube (I used an old mountain bike handlebar). Printed parts consist of the toprail mount compents, the transducer-to-tube bracket, a cable gland (printed in TPE) to protect the transducer cable from the tube edges at the top, and for the rotating mount, a notched TPE disk to "lock" the rotation in up or down position. In addition to the 3d printed parts, hardware needed: one 7/8" tube Inboard mount: one 2 1/2" clevis pin and retaining clip version 1: two 2" 10-24 pan head screws with wingnuts, washers, and internal-tooth lock washers. version2: two 1" 10-24 pan head screws and nylock nuts, instead) version 3 (Rotating Mount): one 3/4" 3/8-24 bolt and 1/4" high nut two 1" 10-24 pan head screws and nylock nuts Transducer-to-tube bracket: one 1 3/4" 10-24 pan head screw, rubber washer, and nylock nut (provided with transducer) The transducer-to-tube bracket is a remix of [jabixby's design](https://www.thingiverse.com/thing:3737927) and can be customized at [onshape](https://cad.onshape.com/documents/a9cfb1eb04744f02214e0498/w/8441291a95e4ccb9b0ce9900/e/50b94aca400a25586dbb46cd). Fusion 360 files included if you wish to customize the railmount for your application.
