I just put up a thread here .... https://www.trainboard.com/highball/index.php?threads/3d-printed-wiring-buss-connectors.135664/ .... for wiring connectors. Felt it fit better there but wanted to link to it here as it is something you can 3D print, Sumner
Hey Sumner, Thanks for sharing these, I've made up some of my own and they work great. Did modify your image to include my own plugs, rather than using a bolt.
Thanks, Not yet, I have a Thingiverse account now but haven't uploaded them yet. No, I run a resin printer at the moment. Elegoo Mars 2 pro. Produces very accurate prints and is much quicker with the mono colour screen. Looking at adding a Ender 3 v2 for the bigger prints I would like to do.
Jeff while you are waiting I do have mine up but you don't print the bolt... http://1fatgmc.com/RailRoad/3D-Printer-2/page-48.html Sumner
https://www.thingiverse.com/thing:4778366 @Jeff Vass Sorry it took a while - first time uploading to thingiverse and had to navigate through all the lesson planning stuff - my ones work well for holding cables down, don't over tighten them otherwise the plug snaps. for cable connections I went with what Sumner did and used hex grub screws to connect the wires together. @Sumner - I've remixed it and linked it back to your design, don't want to take credit for something I didn't come up with.
What are the different boards in this photo? It looks like a servo controller on the left? Interested what the board to the right of the Arduino is for? These connectors are very neat. Would be great to get some printed.
From left to right - 485 TTL converter for the CMRI bus, Arduino Nano, Home made power distribution board for 5v and then up the top just in view an AC current sensor for the block detection. White cable at the bottom is a four strand telephone cable with SDA/SCL signal and 5v/GND for the TTL boards. Yellow/Brown cables are 5v. Red/Black track power.
