Zeppelin Lens Duster
Description
If you print this with flexible filament, it is a fully functioning lens duster. It prints on its tail without supports. There are two versions, one with a hole on the side and one without. The hole acts as a valve, you cover the hole when you squeeze it, and when you release it, the air can come back in through the hole rather than the nozzle. I printed this in TPU and it has the right level of elasticity when you squeeze it. You need to print it normally rather than in vase mode. Vase mode, will make it too soft to spring back into shape after you squeeze it. You can get a bit of control of stiffness by adjusting the extrusion multiplier, print temperature, or the scale. (If you print it larger it comes out less rigid.) If your printer has a moving bed, you may need to print it quite slowly to prevent the it wobbling about as it is printing If you try printing with softer filament than TPU, let me know how it turns out. I can create a version with a thicker wall if needed.
