Gridfinity compatible:

  • 1x3 grid size (and 50mm tall - non stackable)
  • Includes sockets for the standard gridfinity 6x2mm magnets

(I found magnets unnecessary due to the weight of the batteries since I only take out one at a time. I left them in the design since they print without supports, unlike the original gridfinity magnet+M3 combo design)

Holds 4 of the Sony NP-FW50 batteries used in Sony Alpha cameras:

  • Early Sony Alpha A7 series (A7, A7R and A7S generations 1 and 2)
  • Sony Alpha 6000 series: A6000, A6100, A6300, A6400, A6500 (but not the A6600)
  • Sony Alpha A5000 series
  • Sony NEX series (the predecessor for the Alpha

Batteries are slanted forwards for easy removal/return when placed on a shelf or in a deep drawer. I tested with both original Sony batteries and aftermarket ones by Ravpower (from amazon) - the originals have a nice and loose fit and are very easy to remove with one hand. The aftermarket ones fit a bit tighter)

This was printed with the following configuration:

  • eSun PLA+ filament on an Ender 3 S1
  • Print temps: 210 C hot-end and 60 C bed
  • 0.3mm line height, 0.4mm line width
  • 2x walls, 3x bottom/top layers (0.8mm and 0.9 mm respectively)
  • 60mm/s print speed
  • 10% cubic infill
  • no support, no bed adhesion
