8mm Rod - Storage End Caps

thingiverse

This is a container that keeps two 8mm rods together to make storing them simpler. If printed properly, you shouldn't be able to fit the rods into the holder without some effort, requiring a push from the side until they click into place. To take them out, just press down on the middle knob and continue pushing until the rods are at a 90-degree angle to the container, then they'll come out easily. The filament used in these images is Fillamentum Vertigo Galaxy PLA.
