Summary This is a part from another project we were working on. After the project was complete I added a nozzle to the chamber bulb and it become a handy blow out bulb. It is useful for all sorts of cleaning applications, especially removing dust from difficult to reach places. Useful for all sorts of other things as well by just changing nozzle, might be good for reservoir for a water pistol. Bulb printed with TPU @ 0.2 mm layer height @ 60 mm /sec, we used a temperature resistant TPU as the original specs required it hold heated water. Nozzle is PLA but can be anything you wish. Made a quick vid of the printing and testing https://youtu.be/rloedPG-dME printed with the Flex Wheel Extruder http://www.flexwheelextruder.com/ Want something similar printed check out 3D flex's hub https://www.3dhubs.com/service/188137
