Rapid Registration System - AISLER compatible WIP

WORK-IN-PROGRESS

This is very much a prototype, currently it only has holes for the square nuts needed for the slotted dowel pins, it does not provide proper support to the PCB, as I want to figure out an adjustable way to handle it that doesn't block PCBs that might have components already on the side pointing down.

STEP file is provided if you want to remix it to fit your needs.

Printable without any supports, all the holes for the square nuts have been adjusted to be printable without supports, though if you're having trouble with it, you can use tree supports as long as you prepare yourself for a lot of fiddling to get it all out :D

Features

• Supports all 9 pin positions described by AISLER: https://community.aisler.net/t/rapid-registration/42
• All pin positions use large square nuts to prevent pin movement, which might lead to incorrect stencil alignment.
• Uses slotted, threaded, dowel pins for both the PCB and stencil, allowing you to change the spacing to match the PCB and stencil you have.
• Pins for the PCB, if you get the 5mm total length that have 3.6mm part of it being threaded, that stick out around 1mm, meaning it should be slightly below the top surface of a normal 1.6mm PCB while still keeping it fixed in place.
• Pins for the Stencil sticks out a bit more, since stencils are usually very thin, I didn't want it to accidentally get knocked off or similar.
