Are you worried that you'll scratch or dent your precious LTT store water bottle that you probably spent $30 on shipping for?
Have no fear! For now you can print a bumper for your bottle, to protect it from scratches and smaller bumps (Warranty void if you drop it)
Fits snugly for the 40floz version. You can probably scale the model to suit the different versions of the water bottle but these are not guaranteed to work. Do so at your own risk.
Print with TPU or other flexible material. If you use softer material (75A), it should absorb bumps better.
No supports needed.
This is not guaranteed to protect your water bottle from damage, but it has proven to absorb bumps and avoid scratches nicely for me.
