An integrated top-cap + baseplate for Madone SLR bars. I modeled these to use on my Alchemy (i.e. not a Madone). They've survived being printed with PETG, PETG-CF, and Nylon, but please make sure you have your settings dialed and good layer adhesion before you use these on a bike.
Note that the top-cap does have a recessed option for most stem caps. Additionally, the baseplate has holes for internal routing if you have that capability on your frame.
All parts printed out of PETG / PETG-CF / Nylon with a layer height of 0.12mm. Slow-speed is your friend, plus enough temperature to ensure good adhesion. Recomment printing with 5+ walls and high infill for maximum strength.
I do not take any liability for part failures when used on your bicycle.
