This is a set of test lead holders designed to clean up and organize the probes you use every day during electronics testing and troubleshooting. Each of the holders has dovetails to allow it to be mated on the left or right with any of the other items in the collection, with two trays to act as end caps on the left or right. The dovetails provide really easy alignment of the parts and a lot of surface area for applying adhesive to lock the parts in place.
Currently in this collection:
- Oscilloscope Probe Holder, with a pocket for holding the spring hook sleeve
- Multimeter Probe Holder
- Alligator Clip Holder
- Small Tray (left and right end caps)
Each has a mounting hole for a #6 wood screw (McMaster #90031A153), or can be used with a small sized 3M Command Strip.
The parts are designed with no overhang greater than 45° (other than screw hole) so no support structure is required to achieve successful prints. The screw hole isn't a precision feature, so the slight flattening of the hole when printed without supports shouldn't be a big deal.
Suggested Mounting Technique
After printing the assortment of test lead holders that you need, there are several ways you can mount the strip of holders securely.
For total modularity and ease of future customization, the quickest and easiest is to simply use a wood screw on each of the pieces to hold it in place. None of the test leads I have is particularly heavy, so the use of wall anchors isn't really necessary, if you're screwing each one in place.
The next easiest is to use command strips, again, for each of the pieces to mount it in place.
If you want to use fewer screws or mounting strips, you can start to glue the pieces together, with the dovetail providing quick, positive, alignment and a lot of surface area for the adhesive to act on. If you know exactly what you need then go ahead and glue the whole strip together, but if you want to preserve some modularity, then I'd recommend just gluing the sections together by test lead type, and then using a screw or command strip for each of the glued sections.
To build my strips, I used this method...
- If using adhesives, run a line of masking tape over the edge of your work surface to protect it from any potential glue squeeze out.
- Assemble the pieces face down, with the backs overhanging the edge of your work surface. If gluing sections together, apply your glue into the female dovetail then slot the male part in place. The clearance inside the dovetail should spread the glue around sufficiently to create a nice tight bond.
- If you're not using adhesive, run a line of masking tape along the bottom of the pieces to hold them temporarily in place. Apply command strips on the backs of at least every other piece. Having extra command strips handy will allow you to mount and remove the strip of holders a few times to make sure you have enough to make it secure. The amount of clearance in the dovetails ensures they'll always print in a way that allows assembly, but not necessarily tight assembly.
