Mendel XLR + Coax power connector bracket (parametric)

thingiverse

My big power supply that delivers 12V/5A and 18V/15A for the heated print bed via the XLR connector is great, but it's big and noisy due to the cooling fan. When I'm only printing PLA (which is most of the time) I prefer to use a small, silent and nice looking "laptop replacement" power brick, which I connect via a standard coax power connector. Instructions The SCAD allows you to select XLR, coax or both power connectors. In addition, the dimensions of the connectors is parametric if you have a different connector from mine. I've provided STLs for all three options with the connector dimensions I used, or you can use the SCAD to customize. The coax connector I used is a standard "type N" from Radio Shack, 5.5mm outside, 2.5mm inside. Obviously if you get a different power supply you may need a different jack. When printing the dual connector variant, I found I absolutely HAD to use the "cool" module or the last small bit at the top would look all wonky and have no strength at all.
