Hi There, Has anyone tried a 3D Printing Pen? I'm trying to find one and there are a lot of varieties in Amazon. This looks really fun and creative for my 3yo. Any feedback on 3Doodler or Creopop? I found this useful review and trying to compare some things alike - https://thewiredshopper.com/best-3d-printing-pens/

They all all basically function the same but differs in cost, quality, battery life, and ink.
