XT60 heat plate mount for strain relief by Rexipus

Last crawled date: 3 years ago

This thing will securely hold an XT60 connector on the side of my printer's heated bed, so that the wires going to the solder pads cannot be stressed by anyone or anything pulling on these wires, and so that the heated bed will be removable for maintenance or whatever.
To this end I used an XT60 connector, which is rated to support way more current than will flow through these wires to the heated bed. I designed this plastic mount to hold the XT60 connector firmly, using a screw hole that is in the heated bed in between the solder pads.
In the photos the screws are way too long. I'll fix that with my dremel tool and a cutoff wheel. Two 12mm and one 7mm M3 screws would be perfect. I didn't have those, so I used longer ones, which I'll trim to length.
As printed originally, the fit of the XT60 connector was a little too tight. Rather than tweak the dimensions in Solidworks in the source files, I simply tweaked the outer wall offset by a small amount to fix the symptom. It fit OK with -.12mm perimeter "horizontal expansion" in Cura.
I included the Solidworks sources in case anyone wants to fix or tweak this in whatever way.
Edit 8 MARCH 2017: just added STEP file versions of the sources for these two parts.
