Tektronix 22xx series Power cable wrapping holder... thingy... I don't know what they are called. Used them on my Tek 2230 and they work well. The design could maybe be improved a little bit, but not by much I think.

Hehe, spooked my friends with an exploding electrolytic capacitor the other day 😁.

On my HP5335A the stem of the power button was broken off. I will surely find a suitable power switch in my spares bin but the button cap is an other history. Anyone knows of a 3D printable version? HP part# is 5040-0201, it is square, about 9mm.

I reproduced the feet of my Solartron 7081. Should technically also fit the 7071 7061 and others.

I'm in the same situation.
I replaced the switch too and need a new button.

I have another 5335A on the bench, so maybe I'll pull the button off that and draw up a 3D file soon.

Stay tuned....
Where does all this test equipment keep coming from?!?

I just drew up the rear foot/handle for my HP/Agilent 8648C, part number 08647-40003, and stuck it up on thingiverse too.
I guess it'll fit some other instruments too.

And a power button for the HP 5335A Universal Counter.

I haven't checked fitment so some experimentation will be needed with the hole that fits over the plunger in the button, let me know how it goes. :)

After getting my hands on two IET Dekapot's, I've had to make new spacer disks to get the "index support" into proper position.
The attached models are about the thickness of 2 or 3 of the spacer disks combined.
If you have no spacers disks and want to use it stand-alone (no additional front panel thickness) the 6mm one should be just right.
I've used the 4.2mm one with one spacer disk to the same effect.
Your slicer should be able to scale each model in just the Z direction to an individual thickness.

Looking at the bad photo I am actually wondering if they were made from the same soft plastic on the 5300's I made new feet for rather than a rubber. What was left of mine basically crumbled into pieces and the rear shot of Daves looks like that same sort of issue?

Edit Adding the 35mm Foot here due to the 1Mb file size limit   |O I will add it to the link index on the front page and leave both available.

Modded Fusion file and both STL'in the Zip for 6mm Long Screw and the Genuine HP screw options.

Hello Bean,

Any chance you could export the file in STEP also? I want to play with it in Alibre but it will not import Fusion360 files directly.
Thanks,
Sam

Replacement BNC Lever for HP/Agilent/Keysight fixtures, will likely fit other brands of fixtures also, this one was specifically to repair a 16143B fixture for a 4338B milliohm meter.

I made a replacement plastic piece for the Tektronix 576/577 curve tracer standard test fixture.

It does not have the provisions for the HV interlock cover but they shouldn't be too hard to add if you want (the scad file is on the site)

If you downloaded it before 6pm EST on 6/2/24, go back and get the V4 file, it has a bunch of issues fixed. 


I also made a replacement plastic ring for the offset mult pot:
