Wireless QI mobile desk charger

thingiverse

Wireless desktop QI charger, designed for Samsung S6, but should be ok for many others with similar dimensions. It needs this module of QI charger: https://www.aliexpress.com/item/DC-5V-Qi-Standard-Wireless-Phone-Charger-PCBA-Circuit-Board-With-Coil-Wireless-Charging-Micro-USB/32786304209.html Parts should be printed in PLA without any support (necessary supports are included in the project), but I recommend to use good cooling during printing. Multicolor effect visible on the photo I obtained by changing filament during printing. Some tips: please remember to remove supports after printing :) coil case should by glued with body, coil cover is mounted only by crowding on case, coil wires are too short, should be extended by at least 0,75mm2 wires, there is no need to glue coil or PCB. Wires are enough for holding it, LED is inside in the body, it's light is visible through the hole, but it looks much nicer after inserting a piece of transparent plastic cylinder (fi3 x 3mm) into this hole, LED originally added by the Chineses is red/blue, it is possible to swap it with any other dualcolor LED (common cathode), but due to other voltage on blue led, after swapping to e.g. red/green, one of colors will be much more intensive. Trimming of it is possible by adding resistor (47-100ohms) in line with brighter led, bottom cover should stick in the body without screws, "on click". But if it is needed, it is possible to screw it with two short(!) screws M3 with small countersunk head. Holes for these screws are covered, so covers should be drilled out, on the bottom of body there are a places for gluing silicone or rubber pads. It is not necessary, but recommended :) for working it needs good quality classic USB charger (>1A) as a power supply. Too weak charger causes oscillation: charging-not charging-charging-not charging. I'm using this charger from few weeks (with original samsung charger as a power supply), works perfectly :) Print Settings Printer: X3D Rafts: Doesn't Matter Supports: No Resolution: 0,2mm Infill: 33% Notes: PLA, good cooling
