Summary

This design was inspired by the capsule made by Pixxelsnake. I edited his design to make it threaded instead of using an O-ring because I didn't have any, and then made a new design that holds four rather than just one.

I shrunk the dimensions for the holder to a "cigarette" that is 100mm long, 11mm at its thickest, and 6.5mm at its thinnest and overall compared to the original the package is 50% larger.

To secure the lid, I used an M3 screw with a side filed flat, and a nut. These were added to the print, mid print, to create a seamless design.

This does mean the lid has to be suspended up on supports with a single layer cylinder in the middle that gets cut away at the end, so that the screw can be put in mid print.

I have since added a version with flat sides to stop it rolling around, this is compatible with the original lid, but I may edit the lid in future also.

I am also putting silicone around the lip of the lid, to create a waterproof seal, however this isn't a major concern of mine so if it doesn't last that's no sweat off of my back.

I have also added a lid design for where the screw can be added post print, and a stopper be glued in behind it. It will give you a nice flat bottom surface to mate with the main part, but will have a seam on the top from the stopper, and will be more or less obvious depending on how tight you can get the tolerances.

If you need to edit the stopper to fit the tolerance of your printer, the exact dimensions for the hole in the lid is 5.45mm diameter, 2mm height.

The entire item is printed in eSun PLA+
