<p>This is an adapter to use 18650 batteries in place of most any tube style batteries.The included OpenScad script has support for D cells and C cells in the script. Simply uncomment which ever battery type you have, and comment out the other. The length of the tube is based on the num_cells value.</p> <p>If you need to create a holder with a different outer diameter, add a new block containing your desired values, as so;</p> <p>cell_diameter=XX;</p> <p>cell_length=YY;</p> <p>Be sure to comment out any other cell_XX blocks.</p> <p>I built this in order to upgrade my very old Maglite that used 3D cells and an incandescent bulb. I replaced the bulb with an LED upgrade that works from 4~24 volts. I got the LED bulb and the battery clips off <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a>.</p> <p>I've included STLs for 2~7 D-cell and 2~7 C cell.</p> <p>You can create a tube to use some other cell types by modifying the battery_diameter variable.</p> Category: Other
