Simple Hinges[edit]

Status
This OSAT has been designed but not yet tested - use at own risk.
This OSAT has been prototyped.

You can help Appropedia by contributing to the next step in this OSAT's status.

Abstract[edit]

  1. Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
  2. Picture of completed print using

Bill of Materials[edit]

  1. PLC Plastic 32 grams
  2. Screws
  3. Bolt
  4. File:DoorFastener.stl
  5. File:DoorHinge.stl

Tools needed for fabrication of the OSAT[edit]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. PLC Plastic
  3. Mounting Screws

Technical Specifications and Assembly Instructions[edit]

  1. Load the files in Openscad
    • Will have to edit these one at a time
  2. Change the parameters to what will suit your needs
    hinge_scale: changes the size of your door hinge
    (minimum accepted value is 1, creating a door hinge with dimensions 0.236" x 0.4409" or 6mm x 11.2mm)
    screw_radius: radius for the screws for your door
    ensure that the screw sizes are smaller than your hinge dimensions
    door_pin: the pin radius for your connector (needs to be same for both files!)
    door_width: the hinge width (recommended to be same for both files for efficient operations)
    Compile and export as STL
  3. Open up Cura
    In Cura load the STL model
    Create as GCode
  4. Open Up RepetierHost
    Load the GCode, print (est. 1 hour total)

Common Problems and Solutions[edit]

  • May want to consider not using exact spacing for the two hinges.

If the printer is not calibrated exactly, then the hinges will have a lot of friction, or may cause trailing and may not fit together properly.

  • May want to consider adding to the two hinge parts a C style clamp option, if good screws are not possible to come by for the user.

This would allow them to simply require the seven bolts or pins to fasten the door to the hinge.

Cost savings[edit]

  • If your solution is not a low cost one then it is not really appropriate.
  1. 1.05 = (15g + 18g) * (32.00/1000g)
  2. 15.94 for commercial equivalent
  3. Calculate $ savings and % savings
