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.\n* Files may be downloaded off of the Thingiverse here: [http://www.thingiverse.com/thing:577631 Files]\n* Or, the STL file is available here: [[File:Densiometer Mountable 2.stl]]\n\n<gallery>\nFile:Densiometer.jpg|Printed Densiometer\n</gallery>\n\n== Proper Use ==\n\n# Align grid to the portion of canopy you wish to measure.\n# Hold stationary, it is highly encourage to use a tripod with the associated mounts.\n# Count the number of square holes filled over 50%, this number will be the density percentage of the canopy.\n\n== Bill of Materials ==\n\n# 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.\n# 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.\n\n== Tools Required for Fabrication ==\n\n# One 3-D printer capable of printing a 102 mm by 102 mm by 20 mm component.\n\n== Required Skills and Knowledge ==\n\n# Ability to operate a 3-D printing device.\n\n== Printing and Assembly ==\n\n==== Printing ====\n\n* The print is a single component that takes approximately one hour and fifteen minutes to print. It requires approximately 44 grams of plastic.\n\n==== Assembly ====\n\n* For mounting, simply place 6 mm bolts into holes on outside flanges and use nuts to fasten to whatever mount you desire.\n\n==== Common Troubleshooting ====\n\n* 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.\n\n== Estimated Savings ==\n\n* On the low end, a densiometer typically costs around $100. Thus, this print at its highest cost with attachments renders a savings of 97.15%.\n\n{{Page data\n| keywords = 3D printing, forestry, densiometer, foliage coverage, plastic\n| sdg = SDG11 Sustainable cities and communities, SDG15 Life on land\n| organizations = MTU, Michigan_Tech's_Open_Sustainability_Technology_Lab\n| license = CC-BY-SA-3.0\n| language = en\n}}\n\n[[Category:3D printing]]\n[[Category:Forestry]]\n[[Category:Plastic]]"}
