Hello, our lab has a Bpod chamber with 1 port on the back wall and 5 ports on the opposite side (all on separate walls). I'm assuming this is an older / phased-out design that was purchased a long time ago, because I haven't been able to find this model on the current website. Are the CAD files for this chamber model still available somewhere? I looked on github but could only find the 3-port designs.
