Rowing Cox Box Charger plug puller

thingiverse

If you've been rowing in crews for a while, you'll probably know how much hassle can come from cox-box amplifiers getting damaged. When I found both charger plugs of my clubs' 2 coxboxes with dangerously damaged wires due to people pulling on the cable instead of the rubber plug, I knew there must be a way to prevent that. So, I took it upon myself to design my first ever 3D model, which is why this product has taken shape in Tinkercad. As it stands, it's a 3-piece design, created this way so all parts can be printed in an optimal orientation for strength (I only use PLA). The strain relief base and the pulling tab snap together; I had to do minor trimming to get things to fit. Your results may vary. The plug is then inserted into the strain relief and the cap is slid into place from the top, where it will snap into place. If everything goes well, it should do a good job holding the plug in place. Keep in mind that the rubber expands and contracts with temperature; I found the tightness of the hold varies over time. Printing recommendations: * Pulling tab: print lying on its back for optimal strength in pulling direction. * Strain relief base: print with the cylindrical hole in the vertical direction. * Strain relief cap: print standing up. Assembly recommendations: * Test assemble everything to make sure it fits. * Take apart, glue contact interfaces, and reassemble around the plug.
