That one is just "PLA+" so it definitely won't handle any significant heat. It's probably only good to like 100 degrees or so at best (inside the cubby).

So after I play around with it a bit I am planning on getting one printed with heat resistant ABS or nylon.

I was more thinking about the phone and vibration dampening ... rather than the heat :)
 
Hmm, that is an interesting prospect. Although vibration should be much less of a concern if the phone is not "clamped" in to something as a portion of the shock is lost just in the ability of the phone to wiggle freely of what it is sitting on.

But I may noodle on that a little. Maybe a thin rubber sheet cut on a Cricut as an overlay.

But my phone case is soft TPU.

... like I said, just a thought :)

I am still working on finding specific connectors for the charger side of the wiring. The bike side uses a common BMW plug that is easy to find, but the connector for the charger side is harder to figure out. My first try was a BMW X1 fog light cable - grabbed a used one and it didn't work. Next attempt is on its way from eBay - I think I found that its an injector plug that is used on BMW, Audi & Volkswagen.

I designed a fancier plate and 3d printed it out. Don't judge me too much, it is my first 3D printer project ever. Also - I purposefully left it kind of with the rough sanded finish on top because I think it goes well with the bike - instead of shining it up...

WOW...!! Looks great.. It would be ideal if your design allowed for the phone cradle to sit deeper within the cubby space; additionally, if you can keep the cradle surface somewhat thinner, this would also allow for a 12V DC wireless charging puck to be easily integrated into the underside of your design.

Your design would allow each R18 B and or TC owner to optimize the placement of the charging puck, based on the individual phone manufacturer, before committing to the mounting position.

How can I get a printed prototype, I'll integrate the charging puck onto it; I think the BMW cooling fan assembly isn't necessary, as long as the cradle has holes drilled through it to allow for air movement?
 
Yeah, I have ideas for other designs too.

My first one may be to keep it simple like it is but add a pocket underneath or something to stash goodies.

I chose to go wired instead of wireless because wireless charging generates so much more heat.

I have holes and grooves in this design to allow for air to move around somewhat but looking at what is underneath there I just don’t think there is a *ton* of airflow potential anyway - just maybe the heat sink of the metal gas tank down there and a little extra room. But without the active airflow from the fan - it may all just be a placebo.

So wired charging producing less heat than wireless is a big part of my design.

I have lots of ideas and am just learning the tools. ;)
 
I have found the male connector that will connect to the oem plug in there.

First - the bike side plug is a BMW 7543312-02 - it is very common, used all over BMW parts. It is also a Mercedes & VWAG part.

The hard part was the charger side plug, but it is often a "fuel injector sensor" connector or housing.

I have found a 3rd party: " Hirschmann 2way 1.2 SealStar MA Connector "

I ordered this one off eBay: "2 pin Connector housing Pigtail For Audi Volkswagen PORSCHE BMW FUEL INJECTOR"

There are others there too: "BMW VW AUDI PORSCHE Fuel Injector Connector Pigtail Plug 2 Way 2 Pin 1-1718643-1"

It is the correct plug. However, I fumbled connecting the wires to the pins and installing them in the connector. They are incredibly tiny and have tight tolerances - I ended up just breaking the pins trying to get them inserted. My wife had lots of fun with the "couldn't get it in the hole" type jokes...

So - I either need to find one pre-wired with a lead (hard) - or try it again a couple times until I can get it right (hard & potentially expensive).

Anyway, that is my progress thus far.

Same here curious as well.. I'm also wondering if anyone know what standard those quick connects are using.. Thinking of replacing the whole insert with a custom one using the 12V to USB smart adaptor and charging head from Quadlock instead.
 
while disassembling this part so i could actually 3D scan it and figure out the connectors - i ripped out the circuit board to take a look at the pins - and realized the data lines is actually connected on the USB port.. anybody have any idea why that would be?

So for future reference, that power connector, is a AMP TE Connectivity MCON 1.2 - 25A automotive connector. Can be bought from Farnell, Mouser, Conrad (Europe), and chines off brands can be found on Amazon and the like.

edit: 61111692238 - part number for a extension cable that could be cut up and adapted to work.

It's basically 12 V DC to power the whole assembly; the "data lines", I would guess is a temperature sensor which drives the fan speed controller ...

Well those datalines actually connects to the phone thru the USB-C connector.. So might be some form of sensor reading and logic.. But not sure how that handshake would work.. The fan controller has a small "heat sensor" that runs thru up the board and on the backside u see a small "vent" like a circular shape with four openings on its side. Figured out the base shape now at least, so gonna try 3D print a couple of holders for different chargers and see what works best..

Will be scavenging this part for power supply and tie it into the connector where the original craddle drew 12V

Motorcycle - Waterproof 12V To USB Smart Adaptor

The Quad Lock Waterproof 12V to USB Smart Adaptor comes with everything needed to power your Quad Lock Weatherproof Wireless Charging Head from your motorcycle, boat or caravan.
www.quadlockcase.eu www.quadlockcase.eu

It can either directly connect to a phone thru the bottom connector or drive a inductive charger with their "mag" lock system that i use on my other bikes.
 
making it real easy for myself so the 3D printed part is nothing fancy at all. Just a piece of plastic with space for the mag charger from quadlock and some place where the wiring can go..

So this is where it ended up.. the 12V to USB module is one of the 8-36V input modules that outputs 5W of power. The charge plate is the quadlock product, and then i made that pigtail after figuring out the connector is a MLOC 1.2, 4mm pitch connector from TE Connectivity.. the phone attaches to the quadlock with magnets and fits in side the bike. Just need to isolate the circuit with some sugru, shrink tube or tape or something.. the Qi charger is capable of 15W.. but i havent found a module outputtin 3A yet..

Bit more expensive than the quadlock pucks, but yes that should work as well, the run off of 12V right away i guess so you should be able to just crimp the contact straight onto it.
Only drawback i suppose is that the "cradle" for the phone must then locate the charge antenna.. in the case with the quadlock u just "mag" snap it to the antenna at the correct spot everytime. Buut should be easy enough to make phone specific craddles that locates that puck on the right spot everytime..
