I created this to help manage the use of the bubble wrap I use for packaging orders. This has been designed for rolls with an internal diameter of around 75mm.
Watch me build it here: Instagram
Construction: This is based on a thrust bearing design with 12 roller bearings. The bearings are kept in place by a cage and the top and lower parts spin independently with an axle bolt securing them together.
Assembly:
- Very little support is necessary for this model.
- You will need to print 12 of the bearing rollers.
- The nut should be tightened as far as it can go. It should not clamp the parts together tightly, they should be free to move independently.
