macroSD / "Push Push" mechanism
Print Profile(4)
Description
About:
This is a scaled up implementation of the "push push" style microSD receptacle. You have probably seen and used these on some 3D printers and many other consumer electronics - now you can get an idea of how they work. This is a real conversation piece - a technology demonstrator. The designs vary for such components, but you can find serial/part numbers to observe, for example: TFP09-2-12B.

Models ought to look really cool, regardless of their educational value or mechanical novelty. This model's beauty warrants boosting, immediately.
Operation:
The mechanism uses a carriage, pushed by the tooth on the card as it is injected. This carriage is connected to a spring that becomes tensioned when the card makes ingress. A small brace, attached to the case and remaining static, is hooked such that the end travels in channels in the carriage. The brace arm bends laterally and vertically a small amount to accommodate movement, while valleys and cliffs dictate allowed movements for each action/state. The carriage also has a hitch that rotates a "lock" arm into and out of place as this all happens, transforming lateral movement from the guide in the case lid to a rotating motion during card injection and ejection. Thanks.
Assembly:
Thank you!
