3D Printed Resistor Tester Stand

[Barry]

I had a transistor lead former years ago that was basically just a small solid block with three holes spaced 0.1" apart.

All you had to do is push the leads into the holes, perfectly formed every time... with that said, I usually just push them into the PCB unformed and let physics take the wheel.

I just use a piece of strip board

This is really cool... you could argue it's unnecessary, I'm sure, but people should do whatever makes the process more enjoyable for them. I have a 3D printer and would love to give this a whirl.

Thanks, when I get to my optimized design, I promise I will post it here.
Just give me a little more time, I've got a few home projects going all at the same time.

What a simple and clever approach!

I could test with a DMM, but I also have a transistor tester that can test other components.

I test every single component. I bend the leads the same way I would anyway, stick it in the ZIF, and bend the leads on the next one while the results display. It goes really quick, and I populate the board while I'm doing it.

Also, if I tested a component for some other reason, like a breadboard or I measure too many, I know the ones in the bag with bent leads have already been tested.

A short update - I still need a little refinement of the design, as while it does bend the leads to the right spacing, the end of the transistor's lead are not fully straight. Here's the prototype in action:

Pic 1: transistor loaded
Pic 2: hand tool fully pushed in
Pic 3: end result

this is friggin excellent. would use.

I did the resistor tester on my anycubic kobra 3 in PETG. No probs at like 150mm/s. Simple enough design.

I printed up a razor guillotine for chopping up repeatable lengths of shrink tubing:

I needed a way of cutting heat shrink tube into repeatable short lengths. It also needed to be safe and not have any exposed blades. the hole is 6mm sq, the largest I could make it without somebody getting their finger in it.It is all 3D printable, The only extras are the guide rods these are...

(I actually did this one: https://www.thingiverse.com/thing:4437039 . But I don't recommend it: the length stop isn't well implemented. The one above looks to be better thought out.)

Woah.

Metal.

Yeah I get that people like testing things to be sure, but if I didn't trust the manufacturer to print the write value on the resistor, I just wouldn't buy from that manufacturer. Checking one or two here and there is fine, but if I had to test every single resistor I used I would be up all night without even firing up the soldering iron.

Ahhh that's what I'm doing wrong.

Kidding aside. You're not just a hobbyist, so your method of operations makes sense. Gotta keep those TBers happy with the latest SushiFX delicacy!

I loved the idea of it, then got to the length-stop comment...
I bet you could perfect it, or come up with something even better.
