eggtimer rocketry 3d models

The fin jig designed by Howard Kuhn has appeared in the Handbook of Model Rocketry for decades. I'm no good with tools, but I'm okay with a mouse and a friend with a 3-D printer. So I thought I'd make the jigs that way, using the dimensions of the...

... motors. Edit: 01-29-2019 - Added .25 motor retainer for use with the Aerotech 24/60 RMS case. Edit: 02-03-2019 - Link to build thread on The Rocketry Forum can be found at https://www.rocketryforum.com/threads/quake-qu8k-50-3d-print-build.150756/.

This is my version of an AIM-9 sidewinder (Based off this thread at The Rocketry Forum):https://www.rocketryforum.com/threads/kn-aeronautics-aim-9l-sidewinder.180366/It is roughly 1/3 scale (just under given commonly available body tube sizes to work...

I wanted my kids to get into model rocketry, so I started gathering materials. As a kid, I had all the necessary parts, but over time, they were lost. I decided to print out most of the components, except for the rocket engines - maybe even those if...

Tis the season. This is designed to fly on an Estes A10-3 - I've not test flown it but it should have the needed kick. Besides the obvious motors, you will need about 2" of 13mm tube (BT-5), a parachute or a streamer and a short length of 1/8" launch...

 They are also useful in sport rocketry for anchoring rail button screws in fiberglass or even cardboard airframe tubes.The dimensions of the nut holders are completely parameterized in the OnShape CAD file:...

I made a sled for a MIssileworks RRC3 Sport Altimeter to fit on the "back" side of a Madcow Rocketry Avionics Bay. It fits nicely in between the screw rods leaving the larger flat "front" of the sled free for whatever activities you want. I...

This case is designed for the Eggfinder Mini GPS tracker, commonly used in model rocketry. It's an attempt at reaching the most compact volume for the mini in a short length. I'll try a longer, narrower arrangement sometime soon and already have a...

Use in Backyard Rocketry The other childhood memory of these film capsules was making Alka-Seltzer-powered "pop rockets". I haven't tested how well these will hold pressure yet, but presumably they will work nearly as well as the real thing. For...

To fly it you would need:-rocket engine (12mm, 16mm or 18mm, tested with 12mm class A and B)-cord (glued to nose cone and the main tube)-streamer or parachute (see model rocketry tutorials for details)-launch pad/rod (there is a tunnel for the rod in...

Check the laws for model rocketry in your country before launching anything. Never stand in front of or behind a rocket and always keep a fire extinguisher on hand. I am doing a project to observe the effects of drag on rockets and I needed some...
