Valve has provided the CAD files for its new Steam Controller and the Puck under a Creative Commons license on GitLab. Now, anyone with a 3D printer can create mods and accessories for the gamepad.
The GitLab repository includes stereolithography (STL) and STP (Standard for the Exchange of Product Data) files for both the Steam Controller and its ‘puck’. The STL format only covers the outer surface of an object, using pure triangle mesh geometry. Meanwhile, the STP files store the true CAD geometry of the pad, such as surfaces and curves while including units, tolerances, and assembly structure, which allows for precise modelling using SolidWorks, Fusion, etc.
On top of the 3D geometry, these files also note off-limits areas that shouldn’t be blocked, such as the status LED location and the space around the USB port where the Antenna is located. Valve also warns against strong magnets in the rear area, as they can interfere with the function of the TMR joysticks.
Offering these 3D files should allow modders and 3D printer owners to create countless gadgets, from basic charging bases and display stands to smartphone holders and custom shells. The sky is the limit. However, Valve isn’t sharing these files without limitations. The licences for the STL and STP files are strictly for non-commercial purposes, so brands wanting to offer third-party add-ons will have to go through other licensing agreements. Those of us creating things for personal use, though, have nothing to worry about.
3D printer owners can also print a Steam Controller shell to see how it feels in hand before committing to its £85 / $99 price tag. Well, assuming you can find one at that price to begin with, since official stock has already sold out, creating room for scalpers to demand as much as £200 for a pad.
This isn’t the first time Valve has shared the 3D CAD files of its hardware. For instance, Valve previously released CAD files for the Steam Deck, which resulted in some creative creations, such as battery pack holders and extra fans for cooling. The company also indicated that it plans on providing CAD files for its Steam Machine, so modders can make their own front panel decorations. I can’t wait to see what clever items modders will come up with.
