1L Bottle Holder (Brine Shrimp Hatchery)

by Hotrian

Holds a 1L bottle upside down, primarily for the purposes of a Brine Shrimp Hatchery. Perfect for breeder aquariums and for raising fry. For this purpose you'll also need a "Co2 bottle cap" for 1L/2L bottles - you can get these for <$1/ea. on eBay if you don't mind the wait. Designed specifically around a 1L Coke bottle, but I suspect most brands should fit fine. The top hole is 90mm so there is a little bit of play allowed. The pegs are 7.75mm wide and the holes for them at 8mm wide. This offered a perfect press fit for me, but I'm actually overextruding a bit right now so I have provided the Fusion 360 file if someone needs it to tighten those tolerances. For proper assembly, you will need: - Printed parts - (1) 1xMiddle.stl - this is the piece the neck of the bottle rests on - (2) 2xTopBottom.stl - this piece is repurposed as both the top and the bottom - (4) 4xArmLong.stl - these arms go between the top and the middle - (4) 4xArmShort.stl - these arms go between the middle and the bottom - (1) [Co2 Bottle Cap for 1L/2L bottles](http://a.co/1ucRAmG) - Airline tubing - (1) Short piece, approx 6" or as desired - (1) Long piece, approx 18" or as desired - (1) [Microball valve](http://a.co/5yE4Mhd) TheKingofDIY has a great video on setting up and using your Brine Shrimp Hatchery [here](https://www.youtube.com/watch?v=G2BKVhFgpVU). I intend to attach more pictures of the assembled hatchery later :P.
