Clamp-on 2x bottles gripper for short distance

I designed this grip to clip on the neck of standard plastic bottles and allow you/ me/ us to carry TWICE the capacity that a normal pair of hands would allow!!

(this solved a very real problem for me - having to run back and forth from and refuel from the sink to water all plants. I hope you find it useful too)

Features:

• It's designed to cope with up to 2 litter bottles
• PLA works just fine - it has some natural flex. 
• Simple geometry by design - easy to print even on non-optimised printers.
• No supports required.
• 10-15 min total print time.
• Print it of all perimeters. That way the strength will be oriented in the right way
• There's a slight chamfer to soften the grip + a slight lip to allow the bottles to snap into position with a satisfying click.

Specifically designed after the nudge provided by a contest - these contests are such good motivation!
