One of the most popular 3D prints for any VR setup is a stock – a long housing for one or both controllers which really adds to the illusion of using a gun in a game.
While these are relatively simple and easy to make, they mostly share the problem of being too rigid when you swap between weapons in a game. A stock made to mimic a two handed rifle (for example) is rather cumbersome when you want to switch to a one-handed pistol, and removing your controllers in the middle of a game every time you change guns isn’t ideal.
Having both controllers permanently fixed to a stock also creates other problems, like limiting mobility if the game requires a gesture to reload.
To try and address this maker Dominicus Tornqvist has created a collapsing stock that is able to quickly switch between these two desired forms, as well as featuring a clever system to quickly attach and detach the front controller.
“I had always wanted a super-quick, super-simple method of ‘attaching’ the secondary hand to the foregrip, based on the FN P90’s simple, compact, ‘thumb hook’ design of foregrip. This would easily hook around your thumb and still allow you to grip the controller and use all of its buttons and inputs unimpeded,” Tornqvist tells us, “Instead of having to slot the controller into a cup or a mount, you would just stick out your thumb, hook it on to the front of the receiver, and you’re good to go. Just as quick and easy to let go.”
You can see how this works with Oculus Touch controllers in the short gif below.
This project started life in Cinema4D as this is what Tornqvist was familiar with. As you can imagine much time was spent on the collapsing mechanism.
Originally the design here was much more complex, but to make it into a finished project would require far too much time to make perfect.
“So I thought, ‘Okay, what’s the simplest, “dumbest” way it could work?’ And thought a spring latch to lock closed,and gravity to lock open. So that is what I ended up going with,” Tornqvist adds.
Once completed printing took around 40 hours to finish. The raw plastic, after removing the supports, just required a bit of sanding to make sure everything worked together smoothly.
Assembled the stock is 11 centimetres tall and 6.5 centimetres wide. In its collapsed form the print measures in at 45 centimetres long, and that can be extended to 65 centimetres. As the design here is very modular, this can be made to be any length you desire to suit your body, the way you play and the controllers you want to use.
A version of the print is also available with a vertical, static foregrip, should you want the adjustable size without the need to quickly remove a second controller.
