In case anyone else finds this thread, hereās the holder Iām currently working on.
So far itās just the bar that has the registration points for the PCB and the stencil, so it doesnāt provide full support under the PCB itself.
- Has mounting points for all 9 sizes listed on Rapid Registration
- Uses larger square nuts than is more commonly used, but feel free to modify the STEP file to make the holes fit the square nuts you have.
- Meant to be used with threaded M3 and M5 metal pins, allowing you to change which set of pin holes to use.
- Work-In-Progress, it does not provide full support for the PCB, as I want to make it adjustable so it doesnāt block using it for PCBs that already have components on the other side.
Here is the link where you can find both STL and STEP file, and some photos of it without the hardware, as Iām still waiting on the dowel pins to arrive. That page also has links to the square nuts and dowel pins Iām using, as well as their dimensions if you want to source them elsewhere.
