A stackable tray for 8 SMD chips QFP-128 or smaller.
The trays stack with a tight friction fit to allow some wear with multiple opening/closing cycles, the lid has the same tight fit for the same reason.
Printing
The tray needs support - the price of low height stackability.
Usability
Ideally the tray should be printed with ESD-safe filament (fancy…).
When printing with non static safe filament, for ESD sensitive components an electostatic dissipative coating such as Licron Crystal should pe applied.
