Button Battery Holder for LED

thingiverse

This is a simple compact button cell battery holder for lighting a LED. The batteries I used are Duracell 303/357, also says SR44/SR44W/EPX76. I needed it to light a rocket that I printed, where the space to fit a battery did not fit a CR232, or AA batteries. Possibly AAA batteries could have fit, but they would have blocked much of the light in the small space inside the rocket. The rocket that I made is this ornament rocket (http://www.thingiverse.com/thing:39238); however, I did enlarge it to be 5.5" tall. Print Settings Printer: Flash Forge Creator Pro Rafts: No Supports: No Resolution: .1 Infill: 30% Post-Printing Insert the leads of a standard LED into the larger circle at one end, with one lead above and below the centerline, while keeping track of where the positive and negative leads are. Connect one lead around to the opposite end, through a switch, and the other to the closest point where the batteries go. Solder in your connections well and use heat shrink tubing to cover exposed wires. Then insert the batteries in the proper direction and try out your light switch. How I Designed This I used Fusion 360 to design this button cell battery holder so it would fit inside the rocket that I printed.
