REAL WORLD USES FOR THE ELECTRONICS EXPERIMENTER
The design can also be enlarged to hold large wires,
but most of the wiring I use in my electronics workshop fit
fine in this design. Plus, since it’s a 3D print, making a new
one if something melts is easy to do. My 3D Print
I printed mine at a 0.2 layer height and 50% fill
because I wanted it solid. I use Simplify3D software to slice
my prints. A slicer takes the .stl file and turns it into G-Code
that the printer understands. It’s like an assembler for a
I used a green PLA but any color would work. The
50% fill makes it a little heavier as well, but after I printed
it I thought I could have edited the .stl file to have space in
the base for metal washers to give it more weight. This is
easy to do as you just pause the print while it’s printing the
base, put the metal washers inside, then un-pause it and let
the print finish, locking the heavy washers inside.
My printed version is shown in Figure 4. It shows wires
in place ready to solder. One flaw, though, was heat shrink
tubing. On the third hand, I could install heat shrink tubing
on the wire and then use a heat gun to shrink it around the
solder joint. The plastic version didn’t like that much as the
plastic quickly gets soft with a heat gun blowing on it. So,
it’s not a perfect solution but it does have advantages over
the third hand. What I ended up doing was sliding the wire
farther out to the side of the mount so the heat shrink was
away from the plastic holder. Then, I could shoot it with
