Description
I designed this frame box for my Speedmax CF SLX 8.0 SL (Size M). It sits right above the bottom bracket and has a sliding lid on the left side. It integrates with the Elite Crono CX aero bottle.
I printed the box using PETG-CF and did a lot of sanding and spray-painting to get a smooth and aero surface. You will need some supports (I recommend tree-supports).
You can use two or three screws to fix the box to the frame.
I designed the box for my specific frame, which is size M. I don’t know if it also fits the other frame sizes. If you try it, please let me know.
I put a lot of effort into this design, and although it is very specific, I still wanted to share it in the hope that others might find it useful too.
