Pocket Lantern

12 Volt Mini Lantern\nI was driven to reimagine a mini lantern within the confines of today's LED panels and batteries, and successfully developed this Pocket Lantern. It is only slightly larger than a bar of soap, utilizes 3-18650 cells to produce 12V, with a 280ma approximately 300 lumen light that rivals any of my D-cell lanterns, and can be comfortably carried in your pocket. The swing-out feet provide added stability. Run time for 2000ma batteries is around 8 hours.\nThe light panel and switch are both recessed so they don't catch in your pocket or get switched accidentally. For overhead use (camping, tenting) suspend by the feet. The switch is offset to allow adding a battery management system later if desired. Use 4mm o-ring for weather tightness. This groove also fits screen door screen spline available at most hardware stores.\nThe light panel used is 40x60mm, available on Amazon, described as "EverBrightt 6-Pack Cool White 1210 48SMD Led Panel Dome Light Bulbs" for $16.99. The round push-button switch is available on Amazon described as "10 Pcs Latching Action SPST Round Red Push Button Switch AC 125V 3A" for $3.99. Any similar products will work just as well.\nShells for the front are included both for the inset 40x60mm panel, and an un-indented 5mm thick shell you can indent yourself. The box is secured by 3mm printing filament on both sides.\nPrinting:\nI printed this on a Taz-6 with PLA, flat side down. Support is only needed for the panel indent on the lid. I printed 5 top layers, 3 side and bottom layers, 30% infill. It is a solid box that prints well.
