Water Rocket Tornado Tube
Description
<b> Always use caution when using 3D printed parts on pressurized components! <b/> For connecting multiple bottles together for water rockets, this bottle coupler is designed with a water-tight seal and well-fitting threads. Two o-rings are to be fitted onto the bottles before screwing on the coupling. O-ring size: 15/16" id. x 3/32" thickness (23.47mm * 2.62mm) Printed at 0.087mm layer height for best thread quality. Larger layer heights will create stringing but still worked in testing. Supports will help printing the O-ring seat on the bottom facing part of the print. More outer layers will increase thread strength and layer adhesion.
