Hi, I am Robin, of Modular Perfection, and I build cases for modular synths, started in eurorack format but have expanded into Kosmo format still using rails as in eurorack for ease of module placement. I have been a woodworker (mainly antique restoration and table making) for over 20 years and started making modular synth cases a few years ago as it ties in very nicely with my obsession for all things synth!
