Toyota Tundra 40Oz hydroflask holder

thingiverse

This rediculous thing is a cup holder adapter for your 40OZ hydroflask. Be sure to measure your hydroflask before printing, as this thing takes up a LOT of TPU. I printed mine on 30% infill density and it barely fits, but it never tips over. I think redoing it with 20% infill density would be ideal as it would let the base give a little. This holder goes up about 70% the side of the 40OZ hydroflask model. It is intended to be semi permanently mounted. Options 1) Decreasing the infill density will make it squishier. Taking it way down will make it not air tight so it will be easier to take on and off. I preferred 30% 2) If you keep the 30% infill density it will lay on its side even when the hydroflask is filled with water.
