Umikot Flair Pro 2 rework (spirographic wdt tool)

This is a remix of the great Umikot by @redfoxdude https://www.printables.com/de/model/481587-umikot-58mm-version-planetary-gear-spirograph-espr (more remix information at the end).

How to use:

1. Use the printed funnel (base) and pour the coffee grounds into the portafilter, then give it a slight tap.
2. Put the Umikot Flair Pro 2 rework on it and spin.
3. Remove the Umikot Flair Pro 2 rework and give the portafilter with the funnel a slight tap if necessary.
4. Remove the funnel and you're good to go

Quick demonstration:

What you need:

(To get a better idea of what you need, watch the beginning of the assembling video)

• Filament: PETG (or PLA, I recommend using PETG)
•  5pcs: M3 x 12 NoCountersunk (M3-0.5 x 12mm flat round head screws)
• 10pcs: 0.35mm * 60mm acumpuncture needles with 20mm handles (I used 0.35 * 75 mm acupuncture needles from amazon, also called “Sterile Disposable Needle Beauty Massage Sterilization Needle for Pain Relief” and cut them)  with 35mm handles and cut them.)

How to print:

I recommend printing all parts with (food safe) PETG, but at least the base (funnel), as it is more heat-resistant and PETG materials are easier to clean (otherwise you can use (food safe) PLA). 

Umikot Flair Pro 2 rework Funnel (Base):

• 0.12mm layers or finest layers you can print in good quality (important for a smooth funnel experience and cleaning)
• 4 top/bottom layers (consider more if you have sticking and bending problems while printing)
• 2 walls (consider more if you have sticking and bending problems while printing)
• 11% gyroid minimum (consider higher for more heft!)
• No supports
• If you have sticking and bending problems slower your print speed and use the optimized brim Version (Umikot Flair Pro 2 rework Funnel (Base) - optimized brim) instead of the auto generated.

Umikot Flair Pro 2 rework Spin Ring:

• 0.16mm layers
• Concentric top pattern
• 4 top/bottom layers (consider more if you have sticking and bending problems while printing)
• 2 walls (consider more if you have sticking and bending problems while printing)
• 11% gyroid minimum (consider higher for more heft!)
• No supports
• If you have sticking and bending problems slower your print speed and use the optimized brim Version (Umikot Flair Pro 2 rework Spin Ring - optimized brim) instead of the auto generated.

Umikot Flair Pro 2 rework Mech:

• 0.16mm layers (turns much smoother than with 0.2mm layers)
• Concentric bottom pattern
• Random seam (for smoother turns)
• 4 top/bottom layers (consider more if you have sticking and bending problems while printing)
• 2 walls (consider more if you have sticking and bending problems while printing)
• 11% gyroid minimum (consider higher for more heft!)
• No supports
• Problems turning?: Simply turn a few times in all directions, this can help quite a bit. A few drops of neutral cooking oil can also help. (If all settings have been adopted, a calibration of the printer could also help - my mech came directly out of the printer (A1 mini) as shown in the video.)

Other Parts (Handle, Stand):

You can use a print profile which works fine on your printer but use 0.16mm layers to match the other parts.

• 0.16mm layers
• 4 top/bottom layers (consider more if you have sticking and bending problems while printing)
• 2 walls (consider more if you have sticking and bending problems while printing)
• 11% gyroid minimum (consider higher for more heft!)
• No supports
• If needed, use an auto generated brim for the Handle

How to assemble:

Watch the assembling guide video (How to assemble Umikot Flair Pro 2 rework) here: 

This video also shows typical problems that can occur during installation (I used a not optimal test print for that).

I sometimes experiment with a different number of needles, because with the small size of the basket, less may be more. 

Have fun and a nice cup of coffee!

I welcome any constructive criticism or pictures.

This is a remix, the Original Model is “Umikot (58mm Version) - Planetary Gear Spirograph Espresso WDT Tool” by @redfoxdude and firstly adopted to the Flair Pro 2 by @Vert (Umikot for Flair Pro 2). This model is using parts of the mech and the spin ring.

A rethought workflow with fewer steps and less mess:

1. Use the base as a funnel and pour the coffee grounds into the portafilter, then give it a slight tap.
2. Put the Umikot Flair Pro 2 rework (mech) on it and spin.
3. Remove the Umikot Flair Pro 2 rework (mech) and give the portafilter with the funnel (base) a slight tap if necessary.
4. Remove the funnel (base) and you're good to go.

• Complete rebuild - it's more than a remix!
• Longer base for a stable fit on the portafilter
• Stronger holder for the needle on the side so that it doesn't break as easily as it used to
• Complete design overhaul - new grip design for all handles without text and fixed outer diameters for an even look
• New stand that the Umikot Flair Pro 2 rework will fit in without base part (funnel)
• Steeper base (funnel), for even better use as funnel.
• smoother spinning due to a longer outer connecting surface, which contributes to a smoother rotation and an other layer high
• No thread for the rethought workflow
• Due to a longer base and the removed thread, base is usable as a funnel
