Fast Change Effector Wiring Connector Holder by Alexander_Mundy

Last crawled date: 3 years ago

A holder for 2 "Aviation" connectors and tubing connection to make the wiring for effector and extruder quick change. It mounts on 2020 extrusion. Designed for my delta so I can quick change between effectors with a direct drive stepper and Zesty Nimble cable drive, or from 1.75 mm to 3mm filament. I included a hole and landing for Berd-Air style cooling tubing. The tubing from the pump to the box will fit snugly over the landing inside and the smaller tubing to the effector fits on a piece of #10 hypodermic tubing. I always design holes that are accessible a little small to allow final sizing with number bits. I drilled the hole to a #30 size and with the hypodermic tubing in a drill friction welded it into the hole. The material I used is PETG and this must be done quickly and without stopping until it is at the depth you want. I am going to use 2 different "Aviation" connectors, one with 9 pins and one with 10 pins so they cannot be accidentally interchanged. The connectors I got are rated for 5 amps per pin which will be fine for a 12V or 24V hot end heater, but some connectors are only rated for 3 amps max and at 12V would not be suitable. The ones I got are from ebay seller giorgio11185
