Non-electronic Parachute Deployment System
Description
<h1>Non-electronic parachute deployment system for water rocket with the use of a tomy timer.</h1> I use it for children's water rocket projects using 3D printing. Works well, easy to print, no supports. You can find the 3d model online here : https://a360.co/3vR2FQ0 . For the drillings of the rocket body, I use a pattern with all the drillingsand I wrap it around the rocket body to mark the drillings. I hope this will give you some ideas to build your own water rocket !
