I wanted a new lamp for my bedroom that was simple and wall-mounted for easy access. Could have bought one, but where's the fun in that? This one is compact, yet bright enough to light my room just as well as the incandescent lamp I had before did.
This object is super simple to print as well as assemble. In addition to the printed parts, you'll need:
- LED strip lights, around 2ft (I can't remember the exact length, but I used 13 "sections" of the strip. They come in 5m lengths for like $7 so you should be fine to just get a single roll) -- These are the kind that come on an adhesive-backed strip that can be cut every 3 lights. I went with normal ones but you could get RGB LEDs for some interesting lighting options.
- Power cord for LED strip lights -- Pretty straightforward, you want your lamp to be able to get power from somewhere (and there isn't much room for batteries inside this thing, though feel free to modify the design to accommodate). Use a power cord designed for LED strip lights. A regular power cord could cause an electrical hazard. Here's the one I used.
- Switch -- The hole for the switch is designed for a 17mm pusbutton on-off switch I found at my local electronics hobby shop. You could probably find one similar fairly easily or simply open the STL file in your favorite editor and scale the hole/inner supports to fit whatever switch you've got.
- Wire -- Regular old copper wire for electronics projects. Should be pretty easy to come by.
- Soldering stuff -- Self explanatory. This is super simple soldering so if you're new to working with electronics this could potentially be a good easy project.
- Electrical tape -- Should always be on hand for soldering projects. You won't actually need any heat-shrink tubing for this one, but you will want some tape to insulate parts.
- Hot glue -- For keeping your wiring and whatnot in place
- Adhesive-backed foam strips -- Often known as Command Strips, they're simple peel-and-stick strips for mounting posters and stuff. I used the small Velcro ones but whatever you have should do.
Ok, and now for the fun part: building it!
- Print both the base and lens pieces with their flat sides facing down. Print the lens at 100% infill in a nice transparent material. Print the base however you like. No support for either piece. The custom supports should snap off relatively easily.
- Cut your LED strips to length. I designed the lamp to fit 9 sections of the strip around the larger part of the inner mount and 2 sets of 2 sections side-by-side on the front.
- Position your strips, peel off the adhesive, and stick into place. Make sure they're nice and firm. Sticking them into place beforehand really helps keep everything in place for soldering.
- Wire it up. I had a whole detailed explanation here of how exactly to wire this thing but I realized it was starting to become a bit long-winded and probably less helpful than it should be. This is an ultra simple circuit. There's a diagram above for reference. All you need to do is connect one positive (+) lead from each LED strip together and one negative (-) lead from each LED strip together so you have a single (-) wire and a single (+) wire. I found the easiest way to do this is to connect one (-) lead from the long strip to the (-) lead on one of the front strips and the (+) lead from the long strip to the (+) lead on the other front strip, then connect both leads on the other ends of the front strips with short wires (see picture) to complete that part of the circuit. Then I stripped off a bit of the middle of both wires, soldered on some extra lengths of wire to go to the switch, and insulated them with electrical tape so they didn't interfere with each other. Then you simply connect one of the wires to the switch, the other to one of the wires from the power cable, and then the other power cable wire to the remaining section of switch.
- Keep it together. Hot glue is great for keeping all of the wires in place, and the added benefit is that if you use too much you can simply run a razor blade at a low angle along the back surface to trim the glue flush.
- Pop the front lens in place. For me it snaps in nicely with a bit of pressure.
- Mount it to your wall with the adhesive strips, plug it in, and enjoy!
