Magnetic kitchen towel roll holder

Print with 3 perimeter lines and ~15% - 20% infill. Note - left an right brackets are not identical, but are mirrored. 

The magnets are 6mm (diameter) x 3mm thick. Not strictly required, but it is satisfying to have your kitchen roll ‘lock’ in place. They also prevent the roll from accidentally unraveling too much. 

Axle is 40mm in diameter

Works well
