This is a tapered cap with Handle for KYZ Design's FF2 High Flow Desiccant Holders. It adds a small handle so they can be installed in the desiccant holders without a tool. They sit almost as flush as the stock version, but go further into the holders to make room for fingers to grab the handle (so a tiny amount of volume is lost).
I included a profile which has 4 caps together on one plate, since I doubt that anyone how uses the holders has just one :D I have about 20 of them by now. If you do not use the profile, note that the part named “mesh” should be printed with no top or bottom layers and 0 or 1 walls, and triangle infill, since it is supposed to be a mesh like area to help with the airflow to the gel beads.
Thanks to KYZ Design for the awesome FF2 High Flow Desiccant Holders! If you are having issues and need some holders, check em out. They hold a lot of silica gel and are easy to install and use with the AMS. The holders fit most spools, they worked on about 90% of my spools, with just a few that are too wide or too narrow. If you are using quite a few of these like I am, it can be less expensive to get a gallon of the stuff, this is what I use, and it seems to be doing well.
