Replacement Knobs, Feet and Fittings for Test Equipment

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.
Tinkercad link here: https://www.tinkercad.com/things/amQ4XpQkk1r-tek-power-cable-standoff

Update: The design has been enhanced. It is more structurally sound and stronger. The screw holes have also been enlarged for an easier fit.

Download the enhanced version instead. It is in a txt format, but all you have to do is change it back to an STL and it'll work fine.

Oct 19, 2024: Newer updates made. Added fillets and made it over-all much more similar to the original. File uploaded as a txt file. Rename it to a step file and all should work fine. This was made in onshape for those of you who want to know. https://cad.onshape.com/documents/d1d59af15a5a6fd574629103/w/f595091c78b25b4bdda1f7a3/e/3fef025c5d04cdd547a2d425?renderMode=0&uiState=67145f2752a9b256796219a9

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....

I have created for my Yokogawa WT130 rear and bottom foot. It will probably WTxxx power meter series and devices in same box.

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.

Prema 5017 foot.

Use M3x6 screw.

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    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,

Ok, here it is.

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.

https://www.printables.com/model/899528-tektronix-576-standard-test-fixture-plate/files

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:

Handle hinge cap for Tektronix 300 series instruments. It won't fit the non-solid-state instruments though.

Another Tek part:
It is the mating adapter/fixture for the Tektronix 7000 series plug-ins. It does not have the sides trimmed, nor the PCB mater and the weird 4-hole thing on the top of the plug-in; does anyone know what that's for?

It seemed to work well when I tested it.

Looking for a set of feet of the HP 3455A Voltmeter.

So far my search is unsuccessful.

Cheers!

It looks like you can use the standard HP clip-in feet like part number 5041-8801 etc.
There may be a few part numbers for this style foot, they all should 'just fit'.

[sneily]

Indeed,,thanks.
I found other comments on this forum indicating there are numerous different part numbers for feet that will fit. This expands my search net considerably and I am now seeing some options available.
Cheers!

[DavidKo]

It make sense. The older feet were darker "brown" with rubber on rear feet. Then the same feet was used for the front and back (without rubber). Last iteration is grey. But the mounting pattern is the same across HP equipment including computers.

[sneily]

I found a set of 4 on ebay of the proper color for my unit (brown or green). And this set includes two of the wire tilt-stands. So happy ending for me.

By the way, for anyone interested, Keysight still manufactures these feet and tilt-stands and you can order new, directly from Keysight. Though I think they only supply gray ones (a dark gray and a light gray).

Cheers

I've recently got a beat-up Yokogawa 7651 from Japan, hence the need for replacement rear bumper and rear feet.
Since the forum doesn't like step files, I've put them in a zip. Please find them attached
