Quạt thổi bụi Bellows với bề mặt mịn

I remixed this very cool and handy model to have a smooth outer surface. This reduces the amount of travels in one layer. Which should result in less stringing when printing with TPU and also is a little faster.

Filament: transparent TPU Shore A98

Print settings:

• nozzle: 0.6
• layer height: 0.18
• wall loops: 4
• Top/bottom layers: 5
• surfaces and infill patterns: concentric
• support: no
