This is a replacement part for the aomway commander fpv googles.
My menu and dvr buttons weren't glued in place so they fell off.
As this part is really small and most home printers wouldn't be able to print this part, you can purchase this replacement button via shapeways.
As it turns out, the printers at thingiverse are really perfect for this design. Based on the comments the final prints "fit like a glove". So feel free to order them on shapeways.
Here is the link to the shapeways item:
