Keystone PVC Endcap

thingiverse

I've gradually put together an Arduino-based trivia buzzer system (think Jeopardy), laboriously crafting the handheld buzzers from 3/4" thin-walled PVC and meticulously routing the wires for the switch and LEDs to a keystone jack at the bottom of each device. A debt of gratitude goes out to jsadusk, whose keystone mounting plate design I adapted to an endcap created using OpenSCAD, with file included. To achieve optimal results, reverse the model 180 degrees along either the X or Y axis so that the flat component prints downwards. The CAT 3 keystone jack sourced from Home Depot snugly fits into the shaft of the PVC pipe, just barely clearing the interior dimensions. This prototype remains marked as a work in progress, as refinements such as smoothing out the top and bottom edges still require attention and improving the OpenSCAD code for better clarity. Two STL files have been provided: an original model that was successfully sliced and printed using my Printrbot despite being non-manifold, and a revised version that has been corrected (keystone_pvc_fixed.stl) to eliminate any manifold issues. Please note that cutting or sanding the inner edges of the keystone mounting plate might be necessary to accommodate the keystone jack securely, based on your specific 3D printing settings.
