LED Air Rocket Adapter

This is an easy to print adapter to add LED's to your compressed air rockets. Allows you to launch at dusk or at night for a rocket light show - plus helps you find it in the dark...
Fits air rockets based on a 1/2" pipe launch tube. Works well with Air Rocket Works compressed air rocket parts: www.airrocketworks.com

Print all 3 parts, Lower LED Housing.STL, Upper LED Housing.STL and LED Bend Tool.STL
Test threads and adjust printer settings if needed.
Locate (3) 5mm LED's and 2 AG13/LR44 batteries.
Bend and trim LED legs using the 3D printed tool. Using the multi-image above, start in the upper left image by orienting the LED with the short leg (adjacent to the flat on the LED) near the top
Bend the long LED leg straight down
Bend the long LED leg to the right to fit in the groove
Bend the upper LED leg to fit in the upper groove
Mark the LED legs between the two arrowheads
Remove and trim the LED legs, then double check length and bends in the tool
Test the LED polarity by checking it across the batteries as shown.
Repeat with 2 more LED's
Install 3 bent LED's along with 2 batteries into the cavity in the Lower LED Housing. Adjust the upper lead so the LED's are not illuminated.
Thread the Upper LED Housing part into place, and adjust LED legs to have it turn on/off the LED's with a twist.
Using superglue, install the lower LED housing into a ABS Body Tube.
Trim and apply sticker fins
Insert foam nose into Upper LED Housing
Turn on and LAUNCH!
