Small Planters and 50 ml Tube Holders: STL Models

This collection gathers small 3D printing projects: miniature flowerpots, multi-size planter sets, and holders for 50 ml tubes. It helps when you are looking for a small STL object for a seedling, a cutting, or a tube kept on a desk. The models differ in size, wall thickness and part count, so the notes below focus on what to compare. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Small Planters and 50 ml Tube Holders: STL Models»

Two families of models appear here. The first is planters: plain one-piece pots, sets printed in several sizes with matching coasters, and cups that use a wick or an inner reservoir for slow watering. The second is lab-style holders: single stands for one 50 ml conical tube, racks that take several tubes at once, and caps or tops that close a tube.

Before printing, look at the dimensions on the model page: outer diameter, height and the inner opening, since a 50 ml conical tube and a round test tube are not the same width. Check whether the pot has a drainage hole or a separate saucer, how many parts need assembly, and whether the overhangs require supports. The author usually lists a material and settings, and photos of real prints show how the walls and threads come out.

To widen the search, try synonyms such as cache-pot, planter, flowerpot, propagation cup, tube rack, conical tube stand or test tube holder. Related terms help too: saucer, drip tray, wick, hex planter, mini pot, lab tube storage. Combining a size with a shape, for example a small conical pot or a narrow tube stand, narrows the results faster than a single broad word.

FAQ

よくある質問

What is the difference between a cache-pot and a flowerpot?
A cache-pot is an outer container that holds a separate inner pot and usually has no drainage hole of its own. A flowerpot normally has drainage and is planted into directly.
How do I pick the right size for a 50 ml tube holder?
Measure the tube you have: conical 50 ml tubes and round test tubes differ in diameter and taper. Then compare that measurement with the inner opening and depth given on the model page.
Do small planters and tube stands need supports?
Many of them print upright without supports, but tall stands, handles and wide overhangs may need them. The model page and the author's photos show where the overhangs sit.
Which material do people use for pots that hold water?
Authors often list PLA, PETG or ASA, and the choice depends on how much sun and moisture the pot sees. Read the material and settings listed on the model page before printing.
