You can add your own ideas to the list, more than one of you can tackle the same tech in a different way, you may improve upon existing designs if you do so in a '''significant''' way. '''Do this by 11/18'''\n# Design 3D printable components with <u>ONLY</u> OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)\n# Create a Appropedia page for your project. (Easiest way to create a page is to search for the name of it and then click on the red link or in the list put double square brackets around it)\n# Include the following sections on your page using the template below (copy and paste wiki markup into your page)\n# Add picture and link to your project page in gallery below.\n# Print component and bring to class - '''Complete and due by 12/4'''\n\n== Grading ==\n\n* 20% Print quality\n* 30% Documentation\n* 25% Design (design for printing, plastic minimization)\n* 25% Function - Is it OSAT? Does it work?\n\nAutomatic reductions:\n\n* 50% no source or the use of non-OS software\n* 10% per day for late\n\n== Gallery ==\n\n Add your image and link the gallery below in a single line after the last one in the list\n<gallery caption=\"777 OSAT 3-D Printable Designs\">\n\nFile:Most-delta.JPG |[[RepRap]]\nFile:Corn-shell.jpg|[[Corn sheller]]\nFile:BasicTentStake angleview.jpg|[[Basic Tent Stake]]\nFile:Basic-pulley.jpg|[[Pulleys]]\nFile:compar2.jpg|[[Low force snaps for easy assembly/dis-assembly of mating parts]]\nFile:Clips.jpg|[[\"Backpack\" Snap-fit Clips]]\nFile:Fig_9(11).jpg |[[Chicken Feed Holder]]\nFile: Hub.jpg |[[Bicycle Hub]]\nFile:ModeledProsthetic_limbprosthetic.png |[[Limb Prosthetic]]\nFile:Pedal4r.JPG|black mamba bicycle pedal[[Black Mamba Bike pedal]]\nFile:bike_7up.jpeg |[[7up]]\nFile:Umbilical Cord Clamp.jpeg|Umbilical Cord Clamp\nFile:Newspaper_Briquette_Maker_Prototype.jpg|[[Newspaper Briquette Maker]]\nFile:Tool Cutting.JPG|[[Field Dressing Tool]]\nFile:Twfuller_spigot_2.jpg |[[Contoured Spigot for 5-gallon buckets]]\nFile:Wrench_012.jpg|[[Lightweight Wrenches]]\nFile:OShoe.jpg|[[Open source hoe]]\nFile:Open_Source_Shovel_Handle.jpg|[[Custom Shovel Handle]]\nImage:RatchetTop.jpg|[[One Way Ratchet]]\nImage:Assembly.jpg|[[Cassava Press]]\nFile:Bulb_planter_body_detail.jpeg|[[Bulb/Seed Planter]]\nFile:Completed_shoe.jpeg|[[3D Printed Shoes]]\nFile:Hydro Halo (Prototype).JPG |[[Hydroponic halo ring]]\nFile: sprinkler head.jpg | [[Sprinkler]]\nFile:Brakecallipers black mamba.JPG|[[Brake calliper of blackmamba bicycle]]\nFile: Stethoscope_assembly.jpg|[[Stethoscope]]\nFile:Non-Drive Side Crank.JPG|[[Non-drive side crank]]\nFile:otoscope34view.JPG|[[Appropedia:3D Printed Otoscope|3D Printed Otoscope]]\nFile:ChainTensioner.jpg|[[Bike Chain Tensioner]]\nFile:doorHinge.jpg|[https://www.appropedia.org/Hinges]\nFile:Base_Full.png|[[Saline Water Filter]]\nFile:Water_Wheel.jpg|[[Micro-Turbines for Water Power|MicroTurbine for Water Power]]\nFile:Hand_shovel.JPG|[[Hand Shovel]]\nFile:Rain water collector.jpg|[[Rain water filter/bottler]]\nFile:SeedDrillPoke.JPG|[[Seed Drill Punch]]\nFile:Pelton wheel iso.png|[[Bike Hub Pelton Turbine]]\nFile:printed_splitter.jpg|[[Garden Hose Splitter]]\nFile:Hinge.jpg|[[Compost Toilet Hinge]]\nFile:Blade.jpg|[[OSAT Wind Turbine]]\nFile:Drip_Irrigation_Stake_assembly.jpg|[[Drip irrigation stake]]\nFile:Grip1.jpg|[[Handlebar grips|Handlebar Grip]]\nFile:Wood_WorkingClamp_Parts.png|[[Clamps: \"Wooden\" Handscrew Style]]\n File:PhotoresistorHolder.jpeg|[[Heliostat or Sun Tracker]]\nFile:Drop_spindle.jpg| [[Drop Spindle for Spinning Wool into Yarn]]\nFile:Cutter.JPG| [[PET Bottle Shredder]]\nFile:Densiometer.jpg| [[Simple Forestry Densiometer]]\nFile:Pump_assembly.jpg| [[OSAT 3D Printable Treadle Pump]]\nFile:Knife.jpeg|[[3D Printed Carpet Knife]]\n</gallery>\n\n== Template ==\n\n* ---\n\n Copy the wiki markup below to your page to use as a template\n\n* ---\n\n{{777 notice}}\n\n== Title of the device or system ==\n\nProject developed by [your name linked to your user account]\n\n== Abstract ==\n\n# Paragraph description of the OSAT - why is it Appropriate?

Consider the elegance of IKEA like instructions.\n# Include print time estimate\n# Include assembly time estimate\n# Including drawings or pictures of the device at stage of assembly at minimum.

References should use the <nowiki> and <references /> </nowiki>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:<ref>web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://web.archive.org/web/20021201231338/http://www.eren.doe.gov:80/erec/factsheets/landscape.html</ref>\n\n<references />\n\nBased 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 . Be sure to categorize your device so that it will be easy to find – for example \"Low voltage connection basics\" is categorized in\n\n{{Page data\n| license = CC-BY-SA-3.0\n| description = Old ideas, new tools.
