About This File
My designs I have done for high power rocketry bays led me to design connector blocks specialized for that environment. I have taken one of my older designs and remixed it to mount as a right angle four post block for signal and fan wiring. I do like the WAGOs but only for AC/Mains. This block gives you four isolated posts in a space that fits into a extrusion rail with a M3 hammerhead nut.
Printed Part
- 4_post_Wiring_Block_M3_rail
Other parts
- four M3 thermal inserts
- one M3x12 screw for mounting block
- one M3 hammerhead T-nut
- four M3x6 pan head or button head non-oxide screws (shiny)
- four M3 internal lock washers
- eight M3 brass washers
You can use spade terminals or wrap a loop of wire between the brass washers. Personally, I would use a spade terminal for the controller connection and just strip off the ends of the fan wires, twist them together and wrap it around the post. When a fan goes bad, replacement would be the easist this way.
Of note, I have the panels from Printed Solid shown in the picture. The block is only 12mm high, so it can fit against the panel for use in the electronic section.
