IKEA Upphetta French Press Plunger Top

thingiverse

The plunger top on my 1L IKEA Upphetta French Press carafe broke and mine doesn't seem to be the only one. If the 400mL version also uses a metric M5 thread, I should fit on there too. I made the walls a bit thicker and added a few stiffeners so hopefully it won't break as quickly as the original. The thread is modeled in and works perfectly, but you could also redesign the hole to be undersized or fit your type of threaded inserts. I uploaded the F360 archive too, so you can easily customize parts - for example the top surface. I just set a hilbert curve infill on the bottom layer for a more interesting top. If you have Prusa's powder coated steel sheet, I'd definitely recommend using it to match the lid's and base's appearance.
