universal spring loaded key holder

Hello, this product is still under review. I just wanted to get others' thoughts on it. It should be done in the next following days. Once I get it perfect, I will make a YouTube video on assembly( in the following weeks). This process of creation was amusing, and it brings me happiness to share my creation with the public. bill of materials: PLA, TPU, M3 nuts and screws What needs to be worked on is the locking mechanism to make sure the key does not move while in use. This locking system gets caught in other parts.
