Very nice. Will the 6u spacebar support be center, off-center or both?
thank you. i'll be adding support for both
I'm potentially in 
cheers
Very classic & clean design OP, I definitely dig it! The only thing I'd like to see is some internal weights to tighten up the sound some. Wouldn't even mind zinc weights to just add some extra mass to help dull out the higher pitches while still keeping the price reasonable at your 50 MOQ.
this was originally designed for my friends and relatives who wanted a custom keyboard that wasn't too heavy to bring around to-and-from the office, so I thought adding weights would kinda defeat that purpose. perhaps I could add some replaceable aluminium 'weights' and provide brass/stainless steel weights as optional extras
Ah, I see. I figured there must've been a reason you didn't have a weight designed into this. I'd be more than happy with having replaceable alum weights stock & denser material weights being add ons. Although since you have a prototype ordered already we'll get a chance to see how it sounds as it is designed right now. Never know it might be just fine as is without weights?
