Prototyping fastener

This fastening device offers a swift, non-precise connection option when building or prototyping. Its easy positioning and release capabilities make it suitable for uncertain connections. The fastener features four arms - two straight on the bottom and two curved on top. When inserted into a hole, the bottom arms bend but return to shape upon exit, preventing removal. Top arms bend when parts are in place, maintaining connection. To use, hold by the head and push into a hole; to remove, pinch bottom arms' edges toward the fastener's axis and insert again, followed by pulling out via the head. The fastener can be printed on its symmetry plane and is ideal for prototyping due to its ease of use and lack of similar alternatives. It's also scalable to fit various connection sizes and versatile in applications beyond fastening. Simply adjust a dimension in the model based on usage, print, and enjoy its temporary shaft capabilities if desired.
