These are fast 10-minute printing stick locks orignally designed for the Asus ROG Ally but also works with almost any set of analogue sticks. The rings slide underneath and support the sticks from being depressed when placed into storage or a bag. They allow you to carry your Ally or Steam Deck without needing a case!
The Ally ones work well with the Ally, Switch Pro Controller, and Xbox Controllers.
The Steam Deck variant is slightly slimmer and fits everything else too but will allow some more play on the sticks..
Design Changes from Original
Removed the small groove and slightly enlarged the shape for more stability and easier handling.
