Cube plane puzzle

Nostalgia often stirs when we see small toys in malls, reminding us of our childhood memories. I fondly recall playing with a planar puzzle that had an empty slot for moving pieces through its spaces. It made me wonder why not create a 3-D version to enhance space-perception skills. Stereolithography (SLA) printing would be ideal for this, as it provides high resolution and smooth surfaces, allowing puzzle pieces to move seamlessly without clicking – perfect for prototyping.
