Cutting Parafilm with scissors is time consuming and most vendors demand too much money for a simple box with serrated blades, so I designed my own.
You can use any filament you want. You also require
4x M3 heat-set threaded inserts (4mm holes in model)
4x 8mm M3 bolts
4x M3 washers
2x 50mm serrated blades (look for replacement packaging tape dispenser blades)
Some felt
Glue
Assembly
Print the box, lid and two rollers in any filament. Heat set the four M3 inserts in the front of the box. Screw in your two serrated blades using M3 bolts and washers. If your blades have different dimensions than mine (check dimensional drawing photo) you are welcome to modify the box. I've attached STEP files for easy CAD-software import. Cut two 1cm wide strips of felt, glue them on top of each other to double the height and finally glue them to the lid such that the serrated blades hit the middle of the felt strip. Finally, use some length of 1.75mm filament and insert it through the hinges at the back and use some heat to bend the ends up. Use the two rollers, thin side out, to fix your roll of Parafilm in place.
How to use
Open the lid and pull the required amount of Parafilm out. Close the lid and press down some. While still pressing down, gently pull straight down until the film is cut.
