Hario V60 size 02 + 03 coffee filter holder

Sometimes you just want more coffee. This is why I got myself a second, larger V60. Life became perfect, until I got annoyed by having two stacks of filters in the cupboard. This holder solved this unbearable problem for me; it might help you, too. Printing: The design is optimised for 3 perimeters printed with a 0.4 nozzle. I believe 2 perimeters with 0.6 should work well, too, but I haven't tested it. Bump up the infill to 25-30% to lower the centre of gravity. You might want to print at 0.15mm or thinner to make the arcs smoother. Consider adding a tiny tree support to the lip at the front if your printer doesn't print that overhang cleanly. Design details: Space-efficiency: to my surprise, V60 filters are NOT just quarter circles, one side is longer than the other. This holder orients them so the shorter side is on the bottom and adds a gentle angle (10°) to make sure the filters sit flush against the back. Hand-tuned arc following the filter geometry: I scanned the filters I had and made sure the holder's lip is parallel to the edge of the filter. A seam-hiding fold on the back: paint the seam on the back along the fold between the two halves and it will disappear. No dust accumulation at the bottom: the two holes let dust fall through. Pre-positioned divots for anti-slip pads or felt pads: they don't just help the pads stay in place, but also compensate for any slight bed unevenness. No need to support the divots, your printer should easily bridge them. That lip at the front is not just for aesthetics: it hides the surface blend between the "shell" holding the filters and the fillet on the base. Walls are optimised for printing with 3 perimeters: your printer can just follow the perimeters, instead of adding a tiny infill section. This makes the print faster. Gentle chamfer to hide elephant's foot: even if your first layer is slightly over-squished, it won't be visible. Enjoy your coffee!
