  • Formatting was changed.
  • 3D printing on PRUSA with PETG => set nozzle temp to 240

  • Can use blocks to make cell layout => edit the BLOCK file (open in solidworks, select all files when searching for file in solidworks) to edit the layout of all the cell holder parts at once

  • For my designs, when changing the block file, need to rebuild twice for the files dependent on block file

  • Use driven dimensions in sketches to make linear patterns responsive to changes in the block
