Blendr filler for Bontrager stems

thingiverse

I'm a big fan of the Bontrager Blendr system for mounting things to compatible stems. You can mount a Garmin and a headlight onto your bike without a single rubber band or screw-on mount wrapped around your handlebars, resulting in a really clean look to the front end of the bike. That said, sometimes you don't want or need to mount accessories to your Blendr-compatible stem, so you wind up with a blank space and a hole between your stem and the bars. What then? In my constant quest to see just how many things I can do with 3D printing, I thought I could make a filler for this blank area on a Blendr stem, and here we go. Doesn't serve much purpose other than to fill in the blank area and possibly give your bike a pop of color. Which one to print? Bontrager stems come in a couple varieties, and those varieties have different Blendr mounts, so you'll have to choose the right one. The XXX and Pro stems share a wider mount, while the Elite and Comp stems have a narrower mount. The inserts I've got here say "Pro" or "Comp" to mount to those stems. How to know which stem you've got? The Comp and Elite stems have a 16mm gap between the stem front clamp pieces, and the XXX and Pro have a gap just over 18mm. The Comp/Elite also have a round cutout, where the XXX/Pro is flatter but still somewhat rounded. See the photos for more. I've also included a "Lightweight" version of both stems which is hollowed out on the backside. Doubt it's much of a weight decrease, but it's an option. Printed solid in PLA, the XXX/Pro version is only 5.3g! Also included the original F3D files. If you use these to come up with something new, please post your remix!
