Built to store TZE tape cartridges vertically, thus taking up only two gridfinity blocks width-wise. 10ish degree upward tilt to make labels easier to see and to prevent cartridges from falling forward. As a note, sides are not aesthetically perfect given thin walls (1.5mm), which allows the model to accomadate 10 cartridges rather than 9+dead space. Seemed like a good trade off to me. STEP file also included for further modding.
The author marked this model as their own original creation.
