This is a super fun little bow. The idea was taken from the Zing Fire Tek bow. It really shoots far! I designed my own arrow, but the original Zing arrows are still better, as found here: https://www.amazon.com/Zing-AM169-6-Extra-Arrows/dp/B00JYCE3ZI/ref=sr_1_1?ie=UTF8&qid=1505758623&sr=8-1&keywords=zing+arrows.
Things you need to purchase:
3 feet of elastic tubing 1/8″ OD, 1/16″ ID (https://www.amazon.com/gp/product/B00H4MTBSE/ref=oh_aui_detailpage_o04_s00?ie=UTF8&th=1&psc=1)
2 M4 screws 30 mm long
2 M4 nuts
Everything prints without supports if oriented how they are displayed. Print 4 bushings. Thread the screws through the appropriate holes and through the bushings. The bushings will allow the elastic tubing to slide out as it stretches. Cut 2 lengths of elastic tubing about 13-14 inches long. Feed the tubing down through the back of the bow so it comes out the other end. Pass it around the middle divider and feed it back through to the back. Then tie 3 knots on top of each other at each end to make a nice big knot that catches in the slot.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
