    If you're tired of waiting for a decent wireless charging solution or don't want to overpay for a piece of neoprene, I have a 3D printable pad design here that is compatible with the following Amazon Qi Charger (seems to be the same one that RPM Tesla ships with).



    The charging pad's design is a remix from Adafruit's design (credit given on Thingiverse). I just made it thinner and work with two Amazon chargers.

    There are two designs available on Thingiverse - one is a single-piece design and another is a two-piece design (for easier installation). Both designs work the same.

    Update 07May2018:
    - I made couple of updates to the model on Thingiverse. V2 updated dimensions to be compatible with 200um layer thickness. V3 added "Bolt" icons to be visible from the top side so you can see where to place the phone.
    - Added V3 model rendering to this post.

    Update 11Jun2018:
    - Removing outdated information to be less confusing.

    I really know nothing about 3D printing, but what is the cost on the material you’d use in printing?

    A spool of TPU can cost from $10 - $30, and can be used for much more than this one print. It's a pretty inexpensive way to go.

    I just started 3D printing and it’s CRAZY FUN!

    @SoFlaModel3 A few words of warning: being computer inclined and mechanically inclined are a HUGE PLUS. Minimum software skills require you to download files and reprocess it for printing.

    Regarding mechanical skills, it’s possible to buy preassembled 3D printers that can print out of the box but I STRONGLY recommend that you save the $ and buy a kit that you assemble. Many people may disagree with me but I bought an Anet A8 on sale for under $130 (the kit is currently about $150 here https://www.lightinthebox.com/p/3d-printing-anet-a8-b-high-precision-high-quality-fdm-desktop-diy-3d-printer_p5081190.html ). The reason I advocate self assembly is because you will need to constantly adjust and trouble shoot any 3D printer when it clogs or goes out of alignment and by doing the assembly process, you will be able to fix/upgrade it that much easier. It may take several extra hours to put it together but consider it self education time. Plus, 3D printers are so modular, you will be frequently printing or buying upgrades for the printer.

    Honestly, if assembling the printer yourself is not an appealing process, I would suggest that owning a preassembled printer may also not be right for you because of the constant tinkering and adjustments that are needed.

    A few things I’ve recently printed: some are parts upgrades and the cutesy ones are for my daughter.

    Awesome thanks! Ok, so being in software dev, being a nerd, and having built computers in the past is a plus? ;)

    STRONG PLUS.

    Of course my post was for other members on the fence and not full blown geeks like us. Honestly, the Anet was an amazing bargain. Even at $150, i was thinking about buying another for spare parts. I’ve but in some upgrades already like a bigger power supply and printed off a few things to mitigate weak points in the design. Feel free to PM me if you want pointers or we may start a new thread to not completely hijack this one. I’m printing the Tesla charging bracket as we speak.

    How much research did you do before deciding on that model? I've been wanting one for a while but haven't committed any time to finding a good quality/price option.

    I did a lot of research but, basically, it’s a great starting point and a good 8” size to start with. The smaller 4 inch units will be outgrown VERY quickly and I don’t recommend those. I was apprehensive at first about assembly but there are so many useful YouTube vids about assembling this model, It was a piece of cake. Like putting together an erector set. For about $150, you really can’t go wrong. I get 1kg of PLA material from my local Microcenter for $15 and it works great.

    The biggest concerns are easily addressable and things that should be upgraded on any 3D printer especially to reduce fire risk. I added a mosfet for the heat bed to reduce power going thru the motherboard (less than $10 on Amazon). I got a bigger 30amp power supply (less than $20). I printed my own brackets for the heated bed plug to eliminate strain on the wires which can cause fire risk.

    Some people want to upgrade extruders or this or that but honestly, I’m getting amazing quality prints out of this cheap kit. To get better detail, I printed some frame reinforcements and belt tensioners and I bought some spare extruder heads and tubes because they can get clogged and it’s not worth the $1 to unclog anything more than a simple clog.

    Ok, I updated the model on Thingiverse so the dimensions are compatible with 200um layer thickness.

    Also, added a V3 with little "Bolt" icons visible from top side (so you can see the charger target).

    My slicer tells me that this print will cost ~$1.5 to $4 in material depending what your TPU roll cost is ($20/kg to $50/kg).

    Let me know how this works out!

    Printing it out in PETG because thats what i've got loaded up at the moment. Will be able to test fit at the very least.

    how are the puck's cords routed? it looks like from the thingiverse render the border that holds the pucks is continuous and doesn't have a gap for them to pass thru.

    Looks like the cords would line up with the holes in the tray.

    So did a quick print and test fit before I went to work. I can get pics when I get back home.

    First, the circular areas are way too big for the pucks, the pucks are 69mm and the space is much larger than that.

    Otherwise the pad fits snug in place and the "mount points" are accurate and fit as expected.

    Thx!

    I added versions "x.1"'s to thingiverse with a tighter cup size.

    How much does this weigh? Can you provide the Infill and Shell parameters? I am printing this at the library and they charge by the gram.

    Some of these questions are material and printer specific.

    As I said, my printer went down so I haven't done a print, but this is an extremely simple print, just place the front side on the print bed.

    These are generic parameters that I typically would use -

    Infill use 20% to 25% (Shouldn't need more but shouldn't go below)
    X-Y Shell use 1mm to 1.2mm (obviously 0.4mm nozzle can't print 1mm wall but I wouldn't use 0.8mm wall)
    Z Shell use 1mm to 1.2mm (obviously 0.2mm layer thickness can't print 1.1mm wall)
    What other parameters do they need?

    In terms of weight, this depends on the material - my slicer says ~0.22lb or 33000mm of material.

    I made several updates to the design on Thingiverse and also added a new 2-piece design so installation is easier.
    https://www.thingiverse.com/thing:2897497
    https://www.thingiverse.com/thing:2955572

    Additionally, found a cheaper charger on Amazon.


    Also, I finally have a new 3D printer in-house to print these out. Below are photos. (The dual charger pad shows some under extrusion as I hadn't wait for optimizing the new printer; the single charger pad shows a better print.)

    BTW, using the $10 charger, total material cost for the single charger version is $12 and for the dual charger version is $22.

    Looks Great! But dont you also have the cost of the printer? I for one would not need a printer (that I know of yet). I tried to order something once to see how much to have someone make something small I needed and they were crazy priced. Was cheaper in the end to just buy one. But if you have one at work or other purposes this would be a great alternative to the JedaPad.
