Kinetic Sand Math Learning molds

This is 3D-printable sensory math set designed for use with kinetic sand (or similar moldable materials). It’s perfect for engaging young learners with early math concepts like counting, sorting, spatial reasoning, and one-to-one correspondence, all through hands-on sensory play. This design is a recreation of the popular "Math Molds" found in a Lovevery children's learning play kit, made accessible for everyone with a 3D printer. The pieces are robust and sized to create satisfying, stackable sand blocks. There is no assembly required. I am sorry for the bad picture, I will update with better photos some other time. This is version 1, works great for my kid, but i think the lids (that act as presser tools) can be better. I printed without supports and with PETG but it can be done in PLA and supports can result in a neater lid handle
