This 6x3x9 tray can store two of the caulk tubes used with guns that are standard for silicone, construction adhesive, sealants and other caulk-like chemicals (is there a better name for that kind of tube. If there is, please do leave a comment).
The main features of the design:
Since it's a big model, it won't fit in the standard ender3-like printers so I've attached the full model for bigger printers and also two other models that are pre cut so they can be printed and glued together.
The author marked this model as their own original creation.
