Why I made this
I grow carnivorous plants, mostly Utricularia from section Orchidioides such as U. alpina and its hybrids. These plants form tubers and stolons and hate sitting permanently wet, but they still need constant moisture. Commercial net pots are either the wrong shape, too shallow, or force you into a water tray.
So I designed my own. The result is a square net pot with a huge amount of open wall area, a radial open base, and a separate riser that lifts the pot above the water line. A cotton or synthetic wick runs through the centre of the base and down into the reservoir. The plant pulls up exactly as much water as it needs by capillary action, and the crown stays dry. If you do want wet feet, just place in a tray and water as as normal.
Sizes and print figures
Pots (0.4 mm nozzle, 0.28 mm layers, fuzzy skin on the outside):
Footprint | Height | Filament | Print time |
|---|---|---|---|
50 x 50 mm | 50 mm | 13.4 g | 38 min |
75 x 75 mm | 50 mm | 22.7 g | 58 min |
100 x 100 mm | 50 mm | 34.4 g | 1 h 23 |
50 x 50 mm | 75 mm | 18.7 g | 55 min |
75 x 75 mm | 75 mm | 30.4 g | 1 h 20 |
100 x 100 mm | 75 mm | 44.6 g | 1 h 52 |
Risers (23 mm tall, no fuzzy skin):
Footprint | Filament | Print time |
|---|---|---|
50 x 50 mm | 7.7 g | 15 min |
75 x 75 mm | 15.7 g | 20 min |
100 x 100 mm | 25.0 g | 27 min |
Design details
No supports anywhere. Every wall slot has a pointed top so there is nothing to bridge, and the base spokes run radially so each span stays short.
Fuzzy skin on the outside only. While I am a fan, this is not just cosmetic. The rough surface reads as far less "3D printed" in a display collection, and it gives moss, algae and liverworts something to grab onto. After a season the pots start to blend into the setup instead of standing out. The inside is left smooth so you can still get the substrate out at repotting time.
Radial base with a central wick hole. Maximum drainage and airflow, with a solid enough centre to anchor the wick.
Stackable riser. Separate part, so you can decide per plant whether it gets a reservoir or a wick.
How to use the wick
Thread a cotton or synthetic wick up through the centre of the base, leaving a good tail hanging below.
Fan out the top end inside the pot. Contact area with the substrate matters more than wick thickness.
Soak the wick before you fill the pot. A dry wick takes a long time to start moving water.
Fill with your usual mix. I use live sphagnum over a peat and perlite base.
Set the pot on its riser in a shallow tray and keep the reservoir topped up.
Synthetic wick (polyester, acrylic, or a strip of capillary matting) lasts longer than cotton, which eventually rots and clogs. I just put a piece of filament through it so it can't drop out.
Printing
No supports, no brim needed.
tested with 0.4mm nozzle, 0.28 mm layers.
3 perimeters, 0 % infill. The part is essentially all perimeter anyway.
Fuzzy skin: outside walls only.
I grow indoors so print it mostly on PLA, PETG is probably better.
if you need different sizes, let me know in a comment and I'll see what I can do.
Happy growing!
