Attach lid with 1.75mm filament (I used a small section of polycarbonate filament)

170mm*85mm*27mm
Scalable

Diameter of the hinge is larger on the top shell, allowing it to open more freely

Designed to fit the casio fx-991EX, but will fit most other calculators

PRINT WITH PETG OR ABS - PLA WILL SNAP EASILY

Avoid having a seam inside (or near) the hinge.

The filament may need to be pushed in with a little bit of force. In extreme circumstances, use pliers to push the filament in.

Print the test assembly first
