This water cup holder is designed to fit the stainless steel water cups that we sell on this site.
While this little device will not make it impossible for you to knock over your water cup, it will make it a lot harder to do.
I created this product immediately after spilling my water cut on my workbench a few times ... I finally got tired of spilling water all over my bench so I finally did something about it.
Made from 1/8" laser cut MDF. Assembly required. Assemble with white glue, wood glue, or medium CA ... any glue you would use with wood.
