Amazon Echo Dot Lighting Dock

myminifactory

Good Evening or Morning! (small revision to M3 instead of M4 for the assembly screws) So, this is a LED desktop or night stand lamp for the Amazon Echo Dot v2. I designed this in Fusion 360 with inspiration from the ongoing contest here on MyMiniFactory sponsored by Sindoh. The design was created with 3d printing in mind and only requires minimal support for the micro USB plug on the back of the device. Most any minimally calibrated printer should work well within the tolerance range. The echo dot drops into the base and plugs in as normal. A 12-SMD dome light is used, which can be wired into any 12v adapter with an inline switch if desired. I will also post a 6v (USB driven) light for those with soldering skills or more advanced users to modify the single USB cable to power both the Amazon Echo Dot and the single LED. (optional light sources and upper arms included) I made this since I use the Echo Dot here at my desk for music and/or useless information :). From time to time, I need a bit of additional light to help illuminate my workspace or it could be used as soft mood light as well. More pictures will follow, along with assembly and final product. Easy print with minimal support is recommended. I suggest .15-layer height; 22% infill, 2 or 3 walls, and 4-5 top layers. Please let me know if you have any questions. Materials Required: PLA (or other material of your preference - 85 grams) #1 LED (to fit in a @29mm x 22mm space) - revised arms for other LED options below #2 M3 x 8 for the upper and lower arm joint #2 M3 x 16mm for the body and lower arm joint Wire for LED, approximately 200mm in length, needed for the light housing (I used 28-30 gauge silicone wire from Amazon) Affiliate Links for Amazon Items: LED 12v used - https://amzn.to/2GpCSaS 12v Adapter - https://amzn.to/2SjIZ7j Metric Screws - https://amzn.to/2WMjZVE Wire - https://amzn.to/2t1PzAX PLA (white) - https://amzn.to/2TpjNJI PLA (blue) - https://amzn.to/2t2urul Optional Light Sources for Corresponding Arms: 1.

STL = Amazon LED Strips Upper Arm M3 https://amzn.to/2MLDNDP Assembly Instructions: This is a really straightforward process. I find it best to test fit all of the parts and pieces needed before assembly. I started by soldering the wires onto the LED. Approximately 18 inches of 28 gauge silicone insulated wire in contrasting colors were used, leaving enough for connection to a wall adapter or creation of your own USB cable depending on how you wish to power it. Once the LED wires are connected to the LED assembly, feed the wires through the wire chase starting from the LED cavity through the arm and out the top side. Next, you can then feed the wires from the upper arm through the lower arm by the same process staring at the forked end. Once the wires are complete, you can mount the LED (can be press fit when using the 12v one linked - be careful not to pinch your wires but there should be ample clearance under the light). Once the wire is complete and you are happy with the fit and mounting of the LED, you can assemble or join the upper arm and lower arm by using the 2- M3 x 8mm bolts, one from each side. Once the two arms are joined, you can now install the Echo Dot into the body housing. It's an easier fit to do that before connecting the arm assembly to the body housing. Once you have Echo Dot installed in the housing, go ahead and mount the arm assembly to the body using 2- M3 x 16mm bolts, again one from each side. Mine threaded easily but if you have any issues, I recommend starting the screw in the threads prior to joining the arms. Once the final arm assembly is complete, make the proper electrical connections to the LED and you should be ready to go. Hope you enjoy - if you have any questions please let me know.
