Ender3

Coconut 1 in its corner of the MechArtLab

Coconut 1 – the old workhorse with a 1.4 mm nozzle. Our original Ender 3 has been with SGMK since 2019. It now runs a huge 1.4 mm nozzle. It is not made for fine detail; it is made for fast prototypes and especially for vase mode. A 40 mm test box is done in about 11 minutes.

It's rarely busy, so it's usually free. Go for it! 🚀

Why vase mode?

In vase mode ("spiral vase") the printer draws a single wall in one continuous spiral from bottom to top. No infill, no top, no seam, no retractions. With a 1.4 mm nozzle you get:

• Thick, sturdy walls (1.2 mm extrusion width) with only one perimeter
• Huge layers (1 mm): tall objects grow really fast
• Almost no failures: no travel moves, no stringing

Great for: vases, pots and planters, lamp shades, cups and pen holders, boxes, enclosures and quick size checks for prototypes.

Not suited for: small details, text, objects with a closed top, multiple separate parts on one plate, anything that needs infill or a lid.

Print in 5 steps

1. Get the profile: Download File:SGMK Ender3 1.4mm Vase PrusaSlicer.ini.zip, unzip it and import the .ini in PrusaSlicer via File → Import → Import Config Bundle. (On the public MacBook it is already installed.)
2. Select the presets:
   • Printer: Creality Ender-3 1.4mm
   • Print settings: 1mm Vase 1.4mm Nozzle
   • Filament: 3DJAKE ecoPLA @CREALITY - Aa (works for any normal PLA)
3. Slice your model and export the G-code to the microSD card.
4. Check the bed: clean the bed (no fingerprints), and check that it's level with a sheet of paper if the first layer looks bad.
5. Print from the card in the printer menu. Watch the first layer!

Cooling	fan 100 % from layer 2
Retraction	5 mm @ 60 mm/s (bowden)

Tips

• Scale small models up: at 1.4 mm nozzle size, anything smaller than ~30 mm loses its shape.
• Vase mode only works with one object at a time.
• Models must be "solid" (closed). PrusaSlicer hollows them out automatically.
• If walls are too weak: increase the extrusion width in Print Settings → Advanced up to 1.6 mm.

Maintenance notes

• The Z endstop has been adjusted for the 1.4 mm nozzle (October 2026). No babystepping needed.
• Please do not change the nozzle. If something is wrong, tell Aaron or write in the chat.
