I'm been thinking of ways to make assembly easier and more accurate. Some of the devices I'm using are jiggly when using spec holes, and it's important for the devices to all be as exactly straight as possible (to fit in snug enclosure openings).

My solution; 3D printing an alignment tool.

Using manufacture recommended footprint:

Clips on board and holds switch perfectly upright:

It requires a few hours to get a routine established, but I think it's a good investment when you have 13 different devices. The switches will always be exactly upright.

It might not be a big deal when you're only doing a few devices, but I've got hundreds of these suckers to assemble.
