holder5.svg is the master copy of the most recent version of the
electrode holder used for silver-wire electrodes in the electrodes lab
for Applied Analog Electronics.

svg files and inch-based dxf files are provided for both the
individual holder and a few simple arrays of the holders.
All the files are created with Inkscape.

holder4.svg is the master copy of the previous version of the
electrode holder used for silver-wire electrodes in the electrodes lab
for Applied Electronics for Bioengineers.

holder4-mm.dxf is a dxf file in mm for laser cutting.

16-holder4.svg contains 16 cloned copies of holder4

16-holder4-mm.dxf is a dxf file (in mm) for laser cutting 16 at once.
It seems that one of the copies (upper left corner) is
repeated in the same spot---possibly a problem in 16-holder4.svg

At UCSC, using the 130W laser cutter, 5.3mm thick acrylic was not
completely cut through everywhere at 8mm/sec.  It would be better to
do two passes of the cutting at 12mm/sec.  The surface lines were
effectively marked at 180 mm/sec 20--25% power.
