Duct tape dispenser for desktop

Duct tape dispenser for rolls with max. 50 mm width and inner diameter 76 mm. You can use 2 or more smaller rolls side by side. Rubber-feets will help against slipping away.

1. glue the 2 pins/axis to the roll holder
2. assemble roll holder into it slots
3. plug the blade to its slot (use right direction, flat side to the front) 

Maybe, the blade is a little too tight, then scale it down a little bit. Or sand it carefully.
