Tealight holder (mostly for LED)

thingiverse

I created these rechargeable tealights for a holiday project, printing them in red to get into the festive spirit. The lid is entirely optional, but its size can be affected by the type of printer used, settings chosen (and filament employed), as well as calibration - so it's worth checking out the "lid_adjustment" variable in the OpenSCAD code for more information. You may need some experimentation to get it just right.
