Soil Block Maker

The soil block maker consists of three parts: a base with the dibbler, a sleeve to form the block and a tamper to compress the soil mixture.

Four sizes are available: 1", 1 ½", 2", and 3".

Each size supports a variety of dibblers:

• A ½" square with depths of 1/8", 1/4", and 1/2"
• A 1" cube for potting up.

The Fusion360 model is provided to generate sizes that are not listed.

Printing Guidelines

The model has been optimized for a .6mm nozzle with a .84mm extrusion width. It prints well with .3mm layers.

No supports with minimal (10-15%) infill.

Instructions For Use

• Place the base on a flat surface with the dibbler facing up.
• Place the sleeve on the base.

• Invert the entire assembly and gently squeeze again.
• Position the block maker tamper side down on a flat surface.
