Yet another travel Aeropress cap and filter holder

thingiverse

Here's another Aeropress cap and filter holder - like the others, it keeps paper filters in place along with the filter cap, as well letting the rubber plunger go all the way through to its uncompressed size. How mine differs is that it's stronger - the "ear flanges" on all of the others are the weak points. Whether by mail or in my bag, I invariably lose an "ear" within a few weeks of travel, making the whole thing finicky as they need all four flanges to hold the cap in place. The one pictured recently survived 3 months backpacking through Europe, showing no signs of giving up soon. I designed the cap flanges so that the unsupported extrusion doesn't have to make as many sharp turns mid-air, and is more of a straight pull. I printed mine with no supports. I don't think I have my printer tuned particularly well, and I was printing PETG, something that I feel prints worse than PLA. At most, I think I just had a few stray boogers to knock off (PETG makes boogers on my printer). I've included the Fusion 360 .f3d so you can improve it or laugh at my design process.
