MPCNC RJ45 Keystone Holder

thingiverse

RJ45 keystone holder for the top of the motors on an MPCNC machine. Like many, I wanted to use cat5 cables to run between my motors and my controller on my MPCNC so if/when I wanted to extend the size, it would just be a matter of using longer cables and longer tubes. I made these keystone holders such that I wouldn't need to buy new screws, so it only sets the screw back about one millimeter, but is still plenty strong to hold the cable/connectors. There are ridges in the body for strength, but requires very little plastic since the rest of it is only two millimeters thick and the result is still quite rigid. These are the keystones I used [Amazon](https://www.amazon.com/gp/product/B07JRD69V6/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&th=1), but I assume this will work with others that have a similar design: There are two versions available, one for a single keystone and one for a double. I know I'm not the first to do it this way, but incase anyone wanted to know how I wired the double keystone, I took the caps off and took a picture to share. It couldn't be more simple, just wired one opposite the other since the opposing motor needs to spin the opposite direction. Obviously, one cat5 goes to the motor on the opposite side of the tube and the other cat5 goes to the controller. If you choose to make this, let me know if there are issues you find. These are very simple and only take about 15 minutes to print. Print flat with the ridges up and there is no need for support. I printed with 20% infill and they are plenty strong for what they are doing. I think the single is about a meter worth of filament and double is just a little more. Printing two of each of my machine with a 5mm brim took almost exactly 5 meters of filament.
