Main applications could be for people from third world countries where there is minimal automation. A shovel helper grip attachment could save a lot of effort by transferring some of the load from the user's back to the well gripped other hand. This in-turn results into lesser fatigue and more productivity.\n\nAlso, the Leaf Claws attachment can function as a big sized leaf collector hand or as even a shovel for damp yards. These type of attachments could also be used to reach certain areas (eg: for maintenance purposes in sanitation) where use of bare hands could have caused infections.\nThe stl files can be downloaded from here: [https://www.thingiverse.com/thing:1183651 http://www.thingiverse.com/thing:1183651]\n\n== Images ==\n\n<gallery>\nFile:Full hand held shovel grip.JPG|Fully assembled hand held shovel grip\nFile:Shovel example.jpg|Example of application of Shovel Helper - Backsaver\nFile:Leaf claws example.jpg|Example of application of a Leaf Claw application - Backsaver\nFile:Handle.JPG|Modular handle arm with three fixture holes\nFile:Shovel helper.JPG|One of the two shovel helper that fits into the modular handle arm\nFile:Leaf Claw.jpg|Leaf Claw that fits into the modular handle arm\n</gallery>\n</center>\n\n== Bill of Materials ==\n\n# 3 bolts: 5/16 inch diameter with approx 5 cm length: 38 cents x 3 = USD 1.14\n# 3 Nuts that fit into those bolts: 21 cents x 3 = USD 0.63\n# Hair band / Rubber band: Free?\n# PLA filament: Approx 50 x 3 grams = USD 3.2\n\n== Tools needed ==\n\n# [[Athena Build Overview|MOST Delta RepRap]] or similar RepRap 3-D printer\n\n== Skills and knowledge needed ==\n\n* Knowledge of FreeCAD and Cura\n\n== Technical Specifications and Assembly Instructions ==\n\nTo Assemble:\n\n# Download the part files provided above in the bill of materials\n# Convert stl files to gcode using software like Cura\n# Print all of the Parts\n# Attach a hair band / rubber band with the handle arm to make it a comfortable grip on the user's wrist\n# Connect the interlocking jaws of whichever tool you want to use\n# Secure with nut and bolt\n\nTime:\n\n* Total print time estimate: 5 hours\n* Total assembly time estimate: 3 minutes\n\n=== Common Problems and Solutions ===\n\n* One must be careful of your printer radius and calibration as a couple of those parts only just fit into my Delta: check how thw first couple of layers print and shrink the models if needed (all be same amount)\n* Sticking to the bed could be a common problem in case of such large prints: Use high quantities of washable glue on bed before printing\n\n== Cost savings ==\n\n# Cost Estimate: USD 5 for two tools\n# Equivalent products in market cost: USD 33 (Backsaver grip: USD 13 and Leaf claw: USD 20)\n# Net savings achieved: USD 28 (Atleast)\n# Similar products online:\n## [https://www.amazon.com/Leaf-Claws/dp/B00D910KTI/ref=sr_1_7?ie=UTF8&qid=1449613392&sr=8-7&keywords=leaf+hand http://www.amazon.com/Leaf-Claws/dp/B00D910KTI/ref=sr_1_7?ie=UTF8&qid=1449613392&sr=8-7&keywords=leaf+hand]\n## [https://www.amazon.com/Leaf-Claws/dp/B00D910KTI/ref=sr_1_7?ie=UTF8&qid=1449613392&sr=8-7&keywords=leaf+hand http://www.amazon.com/Leaf-Claws/dp/B00D910KTI/ref=sr_1_7?ie=UTF8&qid=1449613392&sr=8-7&keywords=leaf+hand]\n## [https://www.amazon.com/Stout-Backsaver-Attachment-Garden-Assorted/dp/B000DEN57S/ref=lp_128061011_1_24?s=lawn-garden&ie=UTF8&qid=1448856619&sr=1-24 http://www.amazon.com/Stout-Backsaver-Attachment-Garden-Assorted/dp/B000DEN57S/ref=lp_128061011_1_24?s=lawn-garden&ie=UTF8&qid=1448856619&sr=1-24]\n\n== References ==\n\n# www.amazon.com\n# www.walmart.com\n\n<references />\n\n{{Page data\n| language = en\n| keywords = 3D printing, backsaver, gardening, leaf claw, modular arm, osat, yard work, pla filament\n| organizations = MOST, MTU, MY4777\n| sdg = SDG03 Good health and well-being, SDG08 Decent work and economic growth\n| license = CC-BY-SA-4.0\n}}\n\n[[Category:health care]]\n[[Category:Gardening]]\n[[Category:Farming]]\n[[Category:OSAT 3D-Printable Designs]]\n[[Category:3D printing]]"}
