Description

PDF

Modeled on a VST basket and refined through about 7 prototypes, this is the dosing ring that I actually use every day.

  • Magnetic so it clings to the basket. Magnets actually just touch the basket for a good hold.
  • Accurately modeled on a VST basket, fits snuggle and wont wiggle loose
  • Thin profile doesn't get in the way of distributing with a WDT tool. Spread grounds all the way to the edge of the basket.
  • Gently curved outer profile is easy to hold when you are half asleep.
  • Overall stylish profile doesn't scream “3D printed”
  • Prints with no supports
  • Uses readily available cylindrical magnet
