This is a label dispenser designed specifically to suit the product "Avery Dispenser Labels Rectangle 49 x 24mm".
The lid is designed to be a friction fit with zero clearance, and I found that after printing the base and lid snapped together solidly.
I've included the FreeCAD (Link Branch) file for anyone who'd like to customise it, but be warned that it's not a well constructed model.
The author marked this model as their own original creation. Imported from Thingiverse.
