Technical Specifications and Assembly Instructions[edit | edit source]

  1. In order to print this OSAT design, both a blend CAD file will be available for download which can be opened with the open source software package blender. Along with this blend file a stl will be provided through a dropbox link for easy download.
  2. To successfully print the file make sure your printer is calibrated for a successful print, ie. the extruder produces enough filament for a accurate and reliable print.
  3. A print time is estimated to be roughly 8 hours at a 15 percent infill rate. Times will change based upon individual printer settings.
  4. Assembly for the OSAT product involves taking the print and screwing in a standard mason canning jar into the top of the product. Optional mounting screws can be screwed into the small holes on the left and right of the product.

  1. Normal price for bee feeders on the modern market ~$20 jar included ~$4 without
  2. A commercial equivalent can be found [here](
  3. Average cost per commercial bee feeder $20, cost to produce a 3d printed bee feeder, $1.25, cost of mason jar 16oz $8.00. Total savings $20-$9.25 = $10.75
