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!
