If you are looking into an DIY alternative to the Revopoint 3D scan markers you may find those: 3D Scanning Marker - Avery Etiketten 3490 - A4.pdf - Google Drive useful. Designed to be printed with Avery 3490 self-adhesive labels. Each DIN A4 sheet will yield 432 markes which habe to be cut out individually.
Tested with Revopint mini, working reliably.
Sounds like you need a Cri-cut or a Cameo Silhouette to cut out all those dots.
Might be able to use these also - https://www.amazon.com/AVERY-Zweckform-Diameter-Self-Adhesive-Permanent/dp/B08QRRLXWW
Just an example, may be cheaper elsewhere.
Wonder if I could cut these with my new laser cutter/engraver…Might be fun to try! Just use a blank sticker sheet…have to change it to our weird american system but that would be fine…
