I've finally gotten around to releasing these formally after much testing of prints and usage.
The Twystlock system is a set of 100% 3D printable gaming accessories that require no printed supports or additional parts. This means no springs to buy and no metal elements to melt in, just access to a 3D printer and a bit of super glue. Originally designed for the Steam Deck, these accessories can be applied to the case of any mobile gaming device.
The Twystlock connector itself is designed as a quick-connect that secures parts together with a simple twist motion, can be fully recreated with affordable home-based 3D printers, and doesn't require complicated supports to print. The first use of this connector has been for the Steam Deck, specifically to supply an alternative accessory platform that is more accessible to the everyday 3D printing hobbyist, however it could be utilized as a connector in almost any environment.
Feel free to download what you like, and if you would like to request a new accessory design, or vote on the next accessory to be created, please visit our Lemmy community at https://lemmy.world/c/twystlock@lemmy.nowsci.com.
This was my first thought as well, so I looked into it. Turns out JSAUX does provide a range of 3d printable models that can quickly connect to the modcase (as well as a template for modeling new attachments). You can see the models here on JSAUX's printables page.
Included models for it include:
A Deckmate adapter.
A wall mount perfect to use when you want to enjoy your games on a TV.
A VESA-styled mount, like the one used on modern gaming monitors, to help you adapt the position of your Steam Deck.
An universal adapter.
A TF card slot for microSD cards.
A hard disk adapter to replace the ModCase kickstand.
I might look at this, but part of this for me was the engineering experience of building the connector along with supportless parts. So I'm not sure how much time I'd put into adapting away from that. Thanks for the suggestion!
