Kind of... Let me explain.
Standable can connect/link to any type of tracker as long as the tracker shows up in SteamVR.
If SteamVR recognizes it Standable can link to it. This includes SlimeVR trackers.
Despite Standable being able to link with SlimeVR trackers, Standable (in it's current state)
cannot drastically improve SlimeVR tracking quality the same way Standable improves 6DOF trackers. This is because 3DOF trackers (SlimeVR) work fundamentally different to 6DOF trackers and as a result would require adding yet another layer of complexity (to the already complex codebase) and some core changes would have to be made to the current Standable framework.
While there is not a perfect solution, some users in the community (

found some workarounds that allow for some basic functionality while using Standable with SlimeVR (if you turn off the SlimeVR feeder app).
I hope to add complete SlimeVR and 3DOF tracker support in the future, though it is not high on my priority list as it would take a considerable amount of time to implement properly.
