Description
If you are restoring a La San Marco SM 90 coffee grinder and are missing the original rubber/plastic feet, this model serves as an exact structural replacement.
As shown in the original manufacturer schematic (Part 106054), these feet slide directly onto the bottom metal flange of the main casing to stabilize the heavy machine and protect your countertop from scratches. The slot is dimensioned to provide a snug, friction-fit grip on the metal edge, just like the original.
Print Settings & Recommendations:
Material: TPU (95A or softer) is highly recommended to replicate the original vibration-dampening properties of the factory feet and prevent the grinder from sliding on the counter. If you don't have TPU, durable rigid filaments like PETG or ASA will also work perfectly for structural support and long-term wear resistance.
Orientation: Print flat on the build plate with the mounting slot facing upwards (as oriented in the STL file).
Supports: None required when printed flat.
Infill: 20-30% is plenty, though 100% infill or extra perimeters will give it a nice, solid feel to support the heavy grinder.
Layer Height: 0.2mm works perfectly.
Installation: Simply slide the slotted end of the printed foot onto the bottom lip of the grinder case.
