Some of you may have seen my Raspberry Pi Aluminum Extrusion Mount I posted on here recently, I have finished the mount for the 4 relay module I will be using to control LED lights and such for my printer via the raspberry pi. It works great!
This mount is easy to use like the last one. I used 4 small wood screws to mount the relay board. I then used two m4 bolts and two t-nuts to mount this to the printer's frame.
Here is my Raspberry Pi mount https://www.thingiverse.com/thing:3186803
Here is the relay board used with this project https://www.amazon.com/gp/product/B06XRYGM2C/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
It has come to my attention that there are several different sized relay boards available, and not all of them will line up with this mount. I am going to upload another version of this file that is 44mmx69mm mounting holes. the file will be called "44x69_4_Relay_Aluminum_Extrusion_Mount" Try changing the sizing of the part in your slicer to make the holes the correct distance for your relay board. If that does not work, reach out to me and I'll modify the design to work for your board. Happy printing!

Uploaded a mount with the mounting holes spaced as 48x68mm as requested by someone. The file name will be "48x68_4_Relay_Aluminum_Extrusion_Mount"
