I use this to store everything from engine assembly lube to PVC Glue Cans to Aspirin, This is a bottle holder that you can stack high, lay vertically or mount to Multi-Board Pegboards using Multi-connect connector. It also include mounting holes to mount directly to the wall if you choose. If none of these appeal to you, simply place a dot of CA In the mating surfaces for a secure stack. I print with 5% in-fill.

I use this for PVC cement cans, assembly lube, brake grease, rubber cement, even aspirin and have finally gotten things out of boxes all over the place and organized in one place.
