Custom made toolbox for Argon18 triathlon bike - specifially made for E117 size L, but should fit other models as well, I'm not sure about other sizes though. It is 185mm tall and can hold an inner tube, 2 CO2 cartridges, 2 tyre levers. 4 places for 10x1mm magnets to secure the lid. It hides nicely behind the Crono aero bottle. I can provide a pdf file with a view from a side so you can print and check how it will fit.Here is a link to the projection from one side: https://drive.google.com/file/d/1P4ccCx2Tj-nff32nej87PzRZSE-qBxPW/view?usp=sharingYou can print it and try to fit between down tube and seat tube. Please ignore the dashed area on the lefthand side of the drawing (just cut it off) . It is just a piece that wraps around the seat tube.
