This is a strain relief sled for a USB-C PD3.0 Trigger Module Board. I bought them from Amazon. [https://www.amazon.com/dp/B0D5QRDLQV/ref=sspa_mw_detail_6?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWw&th=1](https://www.amazon.com/dp/B0D5QRDLQV/ref=sspa_mw_detail_6?ie=UTF8&psc=1&sp_csd=d2lkZ2V0TmFtZT1zcF9waG9uZV9kZXRhaWw&th=1) 

I wanted to use them for a 12 volt supply for my QRP Labs QMX that I built. I needed a way to add strain relief for the wires and could not find a suitable solution. I decided to create my own solution and share it with all of you!  If you have these trigger boards, then all you need to do is print the sled and then use ½" shrink tube to secure it together. It offers strain relief for the soldered wires. If you are using a different sized wire or a different board I have included my Free CAD project file. It is parametric using the spreadsheet called “global” found in the project.

I hope you find this useful.

Assembly:

Solder the wires to the appropriate pads and place the trigger module into the sled as shown below.

Use ½" shrink tube cut to length.

Fit the trigger module and sled into the shrink tube being sure not to cover the opening of the USB-C connector.

Then use a heat source to shrink. (heat gun, hot air rework station, torch, lighter, etc.)
