Parametric cell pack frame

thingiverse

I have successfully printed the impressive 18650 Battery Frame by lewtwo and was about to assemble my battery pack in a 14s5p configuration, but midway through I decided to switch to a 14s7p instead. The next step was to decide whether to add more modules to extend the battery pack or to add two extra rows. I've been eager to learn OpenSCAD for some time now, so I gave it a try with this design. I made sure to keep most of the features from the original design intact. I did leave out the joints, however, as they didn't work well with my printer (perhaps due to warping), so I ended up printing without joints and gluing/welding the modules together afterwards. Some key parameters are: - Cell array size: width/height - Cell diameter: this should work for other cell form factors (although it hasn't been thoroughly tested) - Cell diameter tolerance: print the cells slightly larger to account for printer tolerances - Panel/frame thickness You can generate a complete part if it fits in your print bed or create multiple modules. Use the Punch Side parameter to choose whether you want a full part (0), punched on one side only (1), punched on the other side only (2) or punched on both sides (3). The Reverse parameter is not yet functional, but you can mirror the parts on your slicer to generate code for both sides of the pack.
