Fertilizer/Seed Spreader Adjustable Hole Pattern

UPDATE: As some people experienced tight fitting threads I uploaded a new profile for just the Lid where i almost doubled the tolerances so that the threads fit. I case you need it you can try out the updated lid.

I got tired of spreading fertilizer using improvised tools like shovels or old planting pots, so I designed this dedicated spreader with a capacity of approximately 680 ml (23 fl oz).

 

The model is designed as a simple 3-part assembly that requires no additional hardware or tools. All parts fit together directly. Overhangs are optimized to print cleanly with almost no supports while maintaining a good surface finish.

 

The threaded lid is designed to stop exactly at the correct position, aligning the scoop perfectly. The perforated insert snaps into place with a bit of force, as shown in the GIF.

 

For improved grip and aesthetics, the outer surface features a hexagonal texture.

 

Material choice depends on your environment. If the spreader is stored indoors in a cool place, PLA works well. For warmer or outdoor conditions, PETG, ABS, or similar materials are recommended for better durability.

 

Suitable for spreading seeds, fertilizer, salt, or similar granular materials.

 

Enjoy your gardening season! 🪴
