In that case it's really just the wording that's off.
3D showcase I think much better describes them.
Doki's 3D was in production long before the concert, though. It was made by KarakuriPower, who also does work for holo (Specifically Sora, Kiara, and Ollie).
Also Mint was the one who had the rush job model. She's since shown her new, higher quality model but I can't remember who made it.
