Both Tamiya and Gunze cement bottles “almost” fit in a 1x1 Gridfinity. Even more annoying is the fact that, except for this model by Alchemik, there seems to be no storage design for the hexagonal bottle of Tamiya Cement - aka Orange Cap. So, I took their model and designed a solution that works for my Gridfinity OCD needs:
They are not stackable, because I like easy access at a glance.
Why four bottles and not three or five? Well, I only have four bottles.
The author remixed this model.
The original is meant for HSW. This is for Gridfinity.
