Abstract
Jump rope handles. What more is there to be said? Kids who need exercise and either can't go running or can't leave the house can use these handles if they find a rope. The idea came from the education tab in the UNICEF Supply Catalog where under physical education they had mostly kick balls which could be expensive to replace all the time because of constant use or if it were to get lost. This provides a cheap alternative for either single use or could be used to make a big jump rope for 3+ people at a time.
Bill of Materials
You will need about $2 of PLA. Media:a_cranford_jumprope_v3.FCStd
Tools needed for fabrication of the OSAT
- Jellybox or similar RepRap 3-D printer
Skills and Knowledge Necessary to Make the OSAT
None.
Technical Specifications and Assembly Instructions
When printing it's best to print the handles up-side down with the height at about 140mm (Z coordinate). It's safest to use a raft and print both at once to save time. It will take 4 hours and 8 minutes to print the both of them.
Common Problems and Solutions
Make sure to have a raft so it wont break off while printing.
Cost savings
- If your solution is not a low cost one then it is not really appropriate.
- Estimate your costs
- Find a commercial equivalent
- Calculate $ savings and % savings
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.

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]].
