I made this to keep everything together in one place. The cable holder is 9 X 16mm, the block holder is 24 X 38mm, and the battery diameter is 33.5mm but all sizes are a little less due to plastic shrinkage. It stands 30mm high. Very little infill, with 3 walls it is nearly all solid plastic. I adapted the 8 cell to a 5 cell for anyone needing a smaller holder. I have not printed it, but it is the same minus 3 cells. I printed the model in PLA with no special settings.
The author marked this model as their own original creation.
