Modular 3-in-1 Stands & TPU Pouches
Tactile, drop-resistant, and ultra-portable accessories engineered specifically for SC-32 and SC-6 calculators. Our zero-waste interlocking puzzle stand transforms from a protective shipping box insert into an upright shelf stand or an ergonomic desk typing wedge.
The Three Configurations of the Puzzle Stand
Instead of throwing away packaging foam, StackCalc turns protective shipping inserts into functional workspace hardware.
1. Shipping Mailer Insert
When your calculator kit arrives, the interlocking stand pieces cradle the PCB, keypad membrane, and faceplate securely inside the mailer box, preventing shipping damage without single-use plastics.
2. 78° Showcase & Dock
Assemble the two upright struts into the baseplate for a steep 78° showcase angle on your bookshelf or desk. The rear bay neatly holds the folded TPU pouch so you never misplace your case.
3. 10° Ergonomic Desk Wedge
Flip the struts horizontally to form a low 10° typing wedge. Angles the ST7567A reflective display directly toward your eyes while keeping your wrists flat during calculations.
