Need help: BMC Teammachine SLR01
Hey good people!
Coming from mountain biking (trail/xc), making a stab at road cycling after trying it out with a friend.
Just got hold of a BMC Teammachine SLR01 frame/fork kit that I’m going to build up.
I’m going for Shimano Di2, but I’ve bumped into a pretty awkward problem; the seat post supports internally mounted Di2 battery, but needs an adapter (BMC part number 212500) that is literally impossible to get hold of without shelling out a load of cash (primarily due to horrible shipping fees). As far as I can see, the part is nothing more than a piece of plastic that is supposed to be threaded into the seat post after installing the battery. Some of the dealers that I’ve reached out to operate with a price of $16 for the part and $75 for shipping it to me 😳
The plastic thingy can be seen in all its glory marked with the denomination (2) in the picture above.
I’m reaching out to you to see if it’s possible to get hold of high quality images of the part that could be used as a starting point for a 3D printed replica of the part. Preferably accompanied with a few measurements of the darned thing too.
Would anyone with access to such a bike be willing to help out?
Best regards,
Tom

Here's a thought - don't mount the battery in your seatpost. Chuck a bit of bubble wrap around it and hang a string off it, wedge it down in the bottom of your seat tube, and pull it out with the string.
You don't feel weight as much when it's lower on the bike - it's not a kludge for lack of a part, it's a performance hack
Di2 is fun to mess with.

If you have the seatpost, seems like some inside measurements could be made to give outer limits
for the cylinder size and the battery diameter will give you the ID. Then the thread form obtained
from something soft and moldable or such as partly cured bondo with a release agent (eg PAM
spray or simple green) inside the seat post. You can interpolate the hex part to a standard
size and incorporate the slot seen in the image. I suspect regular user of 3D printers would be
able to plug this data into a design program and print it for you.

Thanks for helpful insights.
I actually found a Deda piece that I may try out in the seat post, if it fits, problem is solved. Otherwise, I may end up slipping it down the seat tube
