Common Problems and Solutions
- A problem I had when printing my hand cultivator was warping and peeling off the bed during the print. If I were to print it again I would try using the brim feature to help reduce this problem.
Cost savings
Cost of creating this hand cultivator
*Filament needed: 126 grams *At a cost of $23 a kilogram the total cost of the tool is $2.89
Commercial Equivalents
*Equivalents range from $3.74 (cultivator 1) to about $21 (cultivator 2) *They range in materials from composites to most of them being made of metal.
Saving amount
*The savings are anywhere from $.85 to $18.11 *The percentage of the cost is from 77.27% of the cost of the cheap one to 13.76% of the expensive one
References
- The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: [1]

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
