top tube bag

thingiverse

I don't care for traditional top tube bags because they're just too bulky for my taste. This one's made with TPU filament using 0.8mm wall thicknesses, and it's designed as a simple box that gets printed totally sealed up. Once it's done printing, take a knife and cut a slit down the middle of the slanted top portion to get at what's inside. To secure it to the bike, use the printed stretchy strap and loop it around two pins on the sides. Then, in the front, cut two small slits and loop some velcro through them and around the steer tube. I skipped a second TPU strap because the steer tube spins and the TPU is grippy, which would twist the bag with it. This was made for on-the-bike snacks - not for heavy stuff like big phones. Fill it up with peanuts or gummy bears!
