Thanks for the extra context. I haven't actually looked at what you at Zappar are doing for a while. Would you care to comment on what the key differences are between Zapworks Studio [1], Zapworks Designer [2] and Mattercraft [3]? Their elevator pitches on those pages feel like they have pretty complete overlap with each other tbh.
