VR GunStock

for Meta Quest 3

I wanted a fun project to work on during ​Thanksgiving break in 2023 and I recently got a Quest 3 ​headset at the time. So, I decided to design my own ​gunstock to play first-person shooter games with!

But design a basic magnetic gunstock would just be ​too basic and not as fun to design. So, I added a ​pump-action mechanism to it by adding a compliance ​mechanism.

There are a few things I want to highlight about ​this little project! The first one is a minor and, dare I ​say, boring part that has a very big impact on the ​gunstock! I am talking about the pin joints holding ​pipes together. What make them special are the 36 ​grooves with 10 degrees increment, allowing me to ​adjust the angle precisely and lock them together ​tightly without slipping.

The smooth surface one I design before adding ​groove cannot hold the weight of the controllers ​when they are attached. So, theses grooves help a ​lot!

Another thing I want to highlight is the pump action ​mechanism. Here I utilize a very simple compliance ​mechanism and a guided rail to create a spring ​loaded slider. It works like a charm but very noisy due ​to the rough surface of the 3D printed parts.

Overall, this project was a lot of fun and I got to utilize ​many minor mechanical designs I picked up ​throughout my engineering journey. Plus, I now have a ​gunstock to make my VR experience more immersive!
