Made from frustration or laziness - hand wrap roller minimalistic version. I trimmed all unnecessary part to secure easy carry in sports backpack and still have ability's to roll 4 meters wrap in under 20 seconds. Insert wrap into roller, put 4 fingers on a roller body securing that tape goes between fingers (check gif and picture) and roll it with other hand. 

Suitable to roll from both sides of wrap, depends how you like it. 

Only 18g of filament! 45min print time without supports or brim. 

FYI. Handle has a tight fit.
