Parametric Coffee Spoon-FreeCAD

I got tired of trying to get 1 ½ tablespoons of coffee with a 1 tablespoon measure. I didn’t want an adjustable measure as that introduces spaces that could hold coffee and that coffee could get “bad” over time. So I designed this to be parametric so I could print whatever size I need if the amount I need changes.

I printed in PLA on my MK3S with a 0.4mm nozzle, 3 perimeters, no supports, 15% gyroid infill, and ironing on all top surfaces. Without the ironing, it takes less than half the time, but I wanted as smooth a finish as I could get.

Color coding in the spreadsheet:

• Black – Amount of coffee desired
• Green – Values that you can adjust
• Blue – Formulas
• Red – Constant

You can enter either the tablespoons or milliliters of coffee you want per level scoop full. If both are entered, the milliliters take precedence.

You can change the green values if you have different printing values or if you want a different handle thickness or width, cup diameter, wall thickness, etc.

You modify the formulas at your own risk, which might break the model.

Don’t change the constant as that is the number of milliliters per tablespoon.
