Description
A Soil Blocker is a device that takes loose compost and turns it in to a self supporting block for seed sowing. This eliminates the need for sowing trays and pots.
In addition to creating a soil block the device creates a small pit in the top of the block into which the seed it to be placed.
Once the seedlings are growing they can be, complete with the soil block transferred to pots or garden all without disturbing the root system.

Materials and methods
This particular design of soil blocker was created using BlocksCAD.
The first step was to decide on a shape for the container for simplicity of holding in the hand and 3d printing, as a result a cylinder was chosen.
Next was the compactor which needed to be comfortable in the hand and easy to hold.
This would be cylindrical as it needs to fit in to the container with the addition of 5 elongated cylinders formed in to the shape of a four leaf clover (the fifth cylinder fills the centre to add strength). The recesses allow the fingers to sit inside and improve the grip on top of this sits a spherical pommel which fits in to the palm of the hand.
In to the end of the compactor is fitted a pointed peg to make the pit in the soil block to accommodate the seed(s).

wepit53383 commented agoIf you're looking for something really different, find an old-style radio program to listen to. These usually tell a story and use really entertaining sound effects. You could check Spotify for a show like "Suspense: A Murderous Revision" or "Sherlock Holmes." https://dltutuapp.com/tutuapp-download/
