WDT tool for your espresso puck prep!  Additional stuff needed: - 7x 0.4mm or thinner acupuncture needles with: - ~30mm or shorter handle (the type without a little knob at the end, like in the photo below) - ~50mm needle (75mm version of the models also available) - Version with smaller holes is available if using much thinner needles, like 0.25mm, which also have thinner handles Bend a little zig-zag into the needles' handles before inserting, and they stay in place well, while still being removable. They are sharp, so be careful!
