Tiny terrarium to be printed in 4 parts.
Bill of materials:
- transparency sheets [required]
- 8x M3 metric screws [required]
- small pebbles [optional]
- activated carbon [optional]
- soil [optional]
- springtails [optional]
Transparency sheet sizes (in mm):
- 58x115 (x2)
- 84x115 (x1)
- 93x73 (x1)
Any generic transparency sheet (film) with a thickness around 200 microns (0.2 mm, 8 mil) or less will do, just make sure that it has no significant tint.
Tips:
- To insert the top cover, you need to flex it slightly as you slide it into place, as it is held in position by overhanging features on two sides.
- Instead of pebbles, use stainless screw nuts in the bottom-most drainage layer to achieve a lower center of mass so that the terrarium is less likely to tip over.
- Apply silicone to the edges of the transparency sheets to make the terrarium watertight.
- Top up the terrarium with water from time to time, ideally at least once a month. The exact amount will vary based on your setup, but there should be some condensation on the inside of the windows most of the time. To begin with, pour enough water into the terrarium to nearly fill the drainage layer.
- Do not plant succulents in a high-humidity terrarium.
- If you want to use thicker acrylic glass sheets (or similar) instead of thin transparency film, you'll want to use the alternate versions of the two "middle" parts that I've included as well (
body-without-slots.stl and top-without-slots.stl).
