Delonghi Dosing Funnel / Tamping Guide Spirograph

This is a remix of the original 54 mm planetary gear spirograph espresso distribution tool, modified to fit and work with Delonghi espresso machines that use the dosing funnel or dosing and tamping guide system.

I created this version for my Delonghi La Specialista Touch, and it has also been tested on the Delonghi La Specialista Arte. It works perfectly on both machines.

Main modifications:
- Adjusted the diameters to fit Delonghi’s 51 mm system
- Increased the base height to properly accommodate the longer needles and ensure correct movement

Needle setup:
- The needle lengths were modified and need to be used longer than in the original version:
 - 94 mm total length
 - 84 mm total length
- The needles should be inserted the same way as in the original design

With these changes, the tool works reliably with the Delonghi dosing system.

This tool helps distribute coffee grounds before tamping using a spirograph-style motion, making puck preparation more consistent compared to simple leveling or tapping.

Fit & real-world use:
- Fits tightly on top of the Delonghi dosing funnel
- I have been using and testing it for over a month without any issues
- Daily usage: 3–5 coffees per day

Tested compatibility:
- Delonghi La Specialista Touch
- Delonghi La Specialista Arte

It may also work with other Delonghi espresso machines that use the same dosing funnel or dosing and tamping guide system, but please compare the shape before printing.

Printing notes:
- Printed and tested in PLA
- No special material is required
- Print with good dimensional accuracy
- Supports should not be necessary depending on orientation

I could not find a version specifically made for Delonghi machines, so I created this remix.
