Features

• Contacts the basket exterior, since internal funnels leave a void in the coffee grounds
• Friction fit to hold basket in place, since magnets barely stick to 304 Stainless Steel
• Funnel doesn't have to be held in place, can be flipped upside down without falling off
• Follows the basket lip geometry to help avoid grounds getting trapped
• Tall enough to not spill grounds during WDT, but short enough for WDT tools
• Vertical interior walls, so grounds don't get trapped on the ridges
• Curved exterior wall to grip for easy removal

Printing Features

• Flat top for bed adhesion
• Thinnest wall is 1.2mm, 3x 0.4mm nozzle widths
• No overhangs, all slopes less than 45 degrees, no need for supports

Notes

The design uses an interference fit since 304 Stainless Steel is only slightly responsive to magnetic fields

Other Designs

These were designed for the La Spaziale

• Orphan Espresso - Stainless Steel, Internal
• SpazGoods on Etsy - External, 66.50mm ID

Most 53mm dosing funnels on Amazon are designed for a Breville and won't fit

There are quite a few internal designs on Amazon that leave a void much larger than the Orphan Espresso

Food Safety

PLA seems to be safe enough for this application based on the following sources, but make that determination for yourself
