D3D Part Library

Introduction

Conditions of satisfaction for complete CAD for a given project means that we have a complete part library:

• Parts - for building Modules, for producing Fabrication Drawings
• Modules - Made of multiple parts, these are sub-assemblies of the Final Assemlby. These are used for Exploded Part Animations, Language Agnostic Instructionals (LAIs), and other work.
• Final Assembly - The completed build. for Exploded Part Animations, LAIs. Note that the Final Assembly may have to use Simplified Assets in some cases to remain workable
• Simplified Assets: Parts, Modules, Assemblies - these are versions with details removed. Some may be grouped to facilitate handling. In some cases they are drawn from scratch as only abstract, blocky models - to save significantly on file size.
• File Size Requirements - all assets meet File Size Requirements for that particular asset type. Files can't be so large that FreeCAD can't open them or work with them effectively.
• File Organization - Spreadsheet of all Assets (both Simlified and Complete assets) is available
• Construction Best Practices - procedures for effective part building in FreeCAD are followed for each file.
• File Build Documentation - Each file is documented for how to create that file, so novices can get up to speed in making modifications. A short video with voiceover is the best way to document a part build. This is important because this creates design literacy in the general populace.

D3D 16" Version

Hint: Once all the parts here are stable, we will create a FreeCAD D3D Workbench which includes a drag-and-drop of every part within FreeCAD

See D3D Integration, Emmanouil Log, Jose Log, Cedric Log for all the source files, and D3D_Instructional_videos_for_April,_29th,2017_Workshop for exploded part animations, and D3D Language Agnostic Instructionals for further documentation.

• 

  Endstop. - FreeCAD - File:D3D End Stop Switch.fcstd

• D3dframe freecad.jpg

  Frame - FreeCAD -File:D3dframe.fcstd. STL - not 3d printer. Another version will be 3D printed.

• 

  Right Y Axis - FreeCAD - File:D3D Right Y Axis.fcstd.

• 

  'M6x18 Axis Hex Bolt - FreeCAD - File:M6x18.fcstd. Marcin plz confirm

• 

  M6x30 Axis Hex Bolt - FreeCAD - File:M6x30.fcstd. 30 mm version connecting X axis to Y axis. EDITED after Marcin's confirmation

• 

  Axis Hex Nut - FreeCAD - File:Axis hex nut freecad.fcstd.

• 

  Magnet - FreeCAD - File:Neodymium magnet freecad.fcstd. Magnet updated to 12mm×3mm

• 

  Flanged Bearing - goes on the idler 3D printed piece. FreeCAD - File:Pulley.fcstd.

• -----------------------------------------------------------------------------
• Extender.jpg

  Flanged Bearing - goes on the idler 3D printed piece. FreeCAD - File:Pulley.fcstd.

• 

  Carriage Linear Bearing - FreeCAD - File:Carriage linear bearing freecad.fcstd.

• 

  Nema 17 Stepper Motor - FreeCAD - File:Nema 17 stepper motor freecad.fcstd.

• 

  X Axis Belt - FreeCAD - File:8mm belt x axis freecad.fcstd. Belt needs to be 6 mm wide, 2mm pitch (GT2 belt)

• Previewfilename.jpg

  Part name - FreeCAD - File:Freecadfilename.fcstd.

• 

  GT2 Pulley Freecad - File:GT2 pulley.fcstd.

• 

  3D Printed Pulley + 3D Printed LinearBearing These are not the same as the files above. FreeCAD - File:3dppulley.stl. File:3dlinbearing.stl

Subparts

• 

  20 Tooth Timing Pulley - FreeCAD - File:20 tooth pulley freecad.fcstd. This is an extruder driver gear, not 20 tooth pulley. See D3D BOM 2 Week BOM for the correct part.

D3D Mini

• 

  Top extruder Mount - FreeCAD - File:D3D Mini Sub-Assembly Extruder Top Mount.fcstd. STL - File:Miniexthold.stl

Deprecated

• 

  Motor Side, short - File:Universal Axis Motor Side short version.fcstd.

• 

  Idler Side Axis Full Size - FreeCAD - File:Idler side printed axis half freecad.fcstd. This probably needs to be converted to the file from Manolis Log with a version history?

• 

  Frame Extender - FreeCAD by Emmanouil Log - File:D3D Axis Extension.fcstd. STL - File:D3D Axis Extension.stl . Extender does not work well, as it is difficult to make it parallel to frame side.
