Little bracket for my rickety wood shelf. You will need 4 items per plateau. I really hope that it will be useful for you!
PS: This project can still be improved even if I consider that my "v3" version is stable now ("work-in-progress" status ~> closed ;D).
------------- limit of the conciseness -------------
PPS: To let you know, I have:
- bought adequate screws at "Castorama" (french DIY shop) and measured them,
- re-measured my shelf to be sure,
- designed my bracket on OpenSCAD,
- exported the file in ascii .stl,
- converted it to a binary .stl thanks to a Ruby script provided by ByteMuse (http://www.thingiverse.com/thing:39655),
- checked that on MeshLab,
- uploaded everything here,
- added a reinforcement in the corner (next day),
- reprocessed the whole loop to provide a "v2" version,
- printed 2 items at "La fabrique du quotidien" (http://la-fabrique-du-quotidien.org/) in an ugly flashy color (but that was for a test! ;D). The design was Ok but the holes were a bit too small and the body needed to be scaled up (25x15x15 ~> 30x16x20),
- reworked (next day) "a lot" my OpenSCAD file to make it "parametric" (play with the "parameters to tune" to see),
- reprocessed the whole loop to provide a "v3" version,
- reprinted (next week) 4 new items at "La fabrique du quotidien" in a transparent color,
- fixed the brackets at home,
- considered finally that the design is good (Ouf! ;D).
Play with the "parameters to tune" in the OpenSCAD file to generate a bracket adapted to your bookshelf. Export as .stl, slice and print.
