Description

PDF

This is a case for button cell / coin cell batteries. It's a remix of the parametric Small-Battery Case by George F with various improvements:

  • Slider rails
  • Windows on the side to check how many batteries you still have
  • A locking mechanism to prevent the crate from accidentally sliding out of the sleeve
  • A thumb slider at the bottom
  • The crate is flush with the sleeve at the back
  • Closed bottom
  • Pre-generated STLs for many battery types
  • Customizable online in Onshape (scroll down for more info)

 

Printing

Make sure your printer is properly calibrated. The two parts have to fit together. Over extrusion or inconsistent extrusion might result in bad fit.

Print the parts in the original orientation. All the STL files are pre-rotated.

Print Settings

  • Material: PLA, PETG, etc.
  • Extrusion width: 0.4mm
  • Layer height: 0.2mm
  • Perimeters: 3 or 4
  • Top / bottom solid layers: 4
  • Infill: 10% (might work without infill too)

 

Pre-generated STLs

There's a folder in the Files tab for each battery type. Multiple versions with different capacities are available for each battery type.

The file naming is as follows:
[NAME]_[TOTAL_CAPACITY]_[COLUMNS]_(Crate or Sleeve).stl

Note: Apart from the ones in the pictures, battery sizes have not been tested. The dimensions were taken from datasheets from the Umtel components library. If you find any incorrect sizes please send me a message. The list of battery equivalents are from Wikipedia.

Available Pre-generated Cases

Depending on the size of the batteries, pre-generated cases are available with a total capacity 64, 40, 32, 20, 16, or 10 batteries and with 4, 2, or 1 columns.
