This design is based largly of old antique hand drills seen [http://oldtoolheaven.com/hand_drills/drillimg/d2Alg.jpg here].<ref>Old Tool Heaven: Hand Drill Available: http://oldtoolheaven.com/hand_drills/drillimg/d2Alg.jpg</ref> This drill is almost completely 3D printable aside from the drill bit.\n\n== Bill of Materials ==\n\n# PLA or ABS Filament (1.75mm)\n# All of the STL files are [https://www.thingiverse.com/thing:1182628 here].\n# Drill Bit OR\n# Piece of flat metal to be used as drill bit (~3mm X ~10mm X ~75mm)\n\n[[File:Drill Spade Bit.jpg|thumb]]\n\n== Tools needed ==\n\n# [[Delta Build Overview:MOST|MOST Delta RepRap]] or similar RepRap 3-D printer\n# Knife/Exacto Knife\n# Soldering iron (optional)\n# File/Grinding device/knife sharpener/rough stone/similar object\n# Flame creating object (ex: candle/lighter/burning stick)\n\n== Assembly Instructions ==\n\n=== Drill Bit ===\n\n# Use a file or other abrasive material to file a point on piece of metal to be used as the drill bit\n# Add re-leaf angels to the back side of the taper\n# Exact angles are not necessary but try to keep the drill bit symmetric\n\n=== Drill ===\n\n# 3D print all of the pieces\n# Assemble all of the pieces as shown\n# Use a small amount of 1.75mm filament to fasten the parts together\n# Use soldering iron to secure filament in place this will prevent the drill from falling apart\n# If a soldering iron is unavailable heating the end of the drill bit with or other piece of metal with a flame will suffice\n# It is recommended to not completely secure the drill bit adapter.(this allows to easily change bits with out the need of a new drill)\n\n[[File:Assembled Hand Drill.jpg|thumb]]\n\n=== Installing the drill bit ===\n\n* CARE SHOULD BE TAKEN WHEN HANDLING HOT OBJECTS\n# Use a flame of some sort to heat up the back end of the drill bit hot enough to melt plastic\n# Carefully align the rill bit with the opening in the bit adapter\n# Firmly insert the HOT drill bit into the bit adapter\n# NOTE: the plastic in the bit adapter should melt and deform as the bit is inserted\n# Hold Dill bit sturdy until the plastic becomes firm\n# Allow the drill and drill bit to completely cool before use\n\n== Cost savings ==\n\n* If your solution is not a low cost one then it is not really appropriate.\n# Estimated Cost About $5\n# Typical commercially $35<ref>typical Hand drill: Hand Drill Available: http://www.sears.com/schroder-heavy-duty-5-16-inch-rotary-hand-drill/p-00934094000P?sid=IDx01192011x000001&gclid=Cj0KEQiAnJqzBRCW0rGWnKnckOIBEiQA6qDBapP8w3DtMTMr1-xd6S4gqMdXAwy2psb5TihqM6AHFvIaAmaC8P8HAQ</ref>\n\n== References ==\n\n<references />\n\n{{Page data\n| keywords = 3D printing, construction, hand drill, tool, drill bit, plastic\n| sdg = SDG08 Decent work and economic growth\n| published = 2015\n| organizations = Michigan_Tech's_Open_Sustainability_Technology_Lab, MY4777, MTU\n| license = CC-BY-SA-3.0\n| language = en\n}}\n\n[[Category:3D printing]]\n[[Category:Construction]]\n[[Category:Plastic]]"}
