The forest densiometer provides a practical, objective way to measure the density of tree canopy. This tool removes all guess work out of determining canopy cover, which is a very useful metric for foresters and construction companies looking to predict how much foliage and tree removal must be done in an specified area.

The essential material needed to create this densiometer is 44 grams of PLA plastic. At an average price of $25 per kilogram, this part costs $1.10.
This part has optional mounting 6 mm bolts. A pair of these approximately cost $1.50. A pair of matching 6 mm nuts will add an additional 25 cents to the bill.
To remain accurate and objective, clean grid lines are a necessity. Proper calibration is a must, along with with minimal peel up. If peel up occurs, this may be limited with application of a glue stick to the print bed or use of a heated print bed.
