Demo (starts at 1:06): https://youtu.be/_FDZzKAFSz4?t=65

Despite a lot of bridges and overhangs, all printed well without supports.
Printed with 0.6 nozzle at 0.2 layer height.

Extra parts needed:

• 3x M3x8 Bolts
• 3x M3 Nuts
• 2x Air Balloons
• 6x4mm Silicone Pipe (can be found in aquarium shops)
• 2ml Syringe
• 4mm pipe from Intravenous Dropper

Assembly tips:

• Smooth out the Tube part with sandpaper, so the Thumb part would slide better.
• If the valve leaf in the Handle part didn't print well, just cut it away an try printing the Plate part.
• Insert balloons into each other. More balloons - more pressure! I could handle no more than 3).
