Bring a touch of greenery to your space with this miniature greenhouse designed to fit a jar as its lid. Perfect for small plants, succulents, or decorative purposes, this model combines simplicity with functionality.

The ring is modeled as a separate object, allowing you to easily mix and match colors. I photoshopped the last image to provide some inspiration for styling your mini greenhouse.

There are print profiles for Regular and Wide Mouth Mason jars.

I used a jar I found at home as the base reference, with following dimensions:  
1. 55,5 mm
2. 46,5 mm
3. 19 mm 

To make this model fit your specific jar, you will need to measure the inner and outer diameters of the jar opening and the Height of the Threading:

1. Outer Diameter (including threads)
2. Inner Diameter

3. Threading Height

   

I recommend using the Measure Tool in Bambu Studio.
Click the Measure-Tool, select the ring of the object you want to adjust and enter the radius of your measurement (diameter ÷ 2).
Make sure to select the outermost ring for the base and pot, and the innermost ring for the ring object. Also, be sure to use the same value for both the base and the pot. I recommend to add 0.4 mm as tolerance to your measurements. 

If this isn’t an option, you can calculate the correct scaling using these formulas:

Ring:

• XY Scale = (Glass Outer Diameter + Tolerance) / 55
• Height ≈ Threading Height / 19

Base and Pot:

• XYZ Scale = (Glass Inner Diameter + Tolerance) / 46.9

For all objects, you can definitely adjust the height (Z scale) as you like, but I recommend using the formulas for the X and Y scales.

Note: Multiply the results by 100 if you need values in percent. All measurements are in millimeters. I used a tolerance of 0.4 mm.

Thank you to @Spacedfallen for testing the fit of the Mason Jar Version!
