01 / THE CONSTRUCTION
The strength comes from the frame. The give comes from the parts between your slab and the case.

See how the frame, flexible contact parts and screws fit together.
A matte PLA rear chassis and front bezel form the rigid shell around the holder.
The inner cradle, front cushion, four corner caps and four side strips use TPU: a flexible printed plastic. It cushions the contact points around the slab.
Eight M3 screws fasten into brass heat-set inserts. Open it, swap the slab, fasten it again. No glue or snap-fit closure.
Four flexible corner caps, held mechanically. No glue.
TPU side strips line the long edges. A front cushion sits between the bezel and slab face.
