Replacement Knobs, Feet and Fittings for Test Equipment

Tektronix TM500 series plug-in pull tab mechanism. This is the newer version that uses spring metal.

STL file in txt format to get around forum restrictions. Change the file back to STL and it should work fine.

Update: The 3D model has been revised. Previously v4 is now outdated. v6 is the new current version. Please download v6.

The change was made to make the coupling mechanism between the pull tab and the latch release more tolerant.

Tektronix 7000 Series Basic Plug-in Chassis 3D model.

https://www.tinkercad.com/things/9XErYBOUfeX-tektronix-7000-series-plug-in

The Plug-in top and bottom part basics are modeled after the 5000 series and TM500 series plug-ins but are just longer to fit the 7000 series. They are split into two parts to make 3D printing easier if need be. I've included the plastic bar and plastic lever that keeps the plug-in latched in in the 3D model. The design will probably be improved later. First thing to be added will probably be the latch release mechanism for the 7000 series.

I have not included a 3D model because then it would be difficult to separate the other parts of it to 3D print. So I'll just add the tinkercad link for better freedom.

The plug-ins seem to fit well in my 7613 so I see no problems. The current latch mechanism works but is still finicky.

In its current state it can be used as a storage or plug-in bay filler.

New entirely revised Tektronix 7000 Series Basic Plug-in Chassis 3D model

I've recently started getting used to the big boys' CAD software, I must say, onshape is much more powerful than Tinkercad.

I recreated the entire model in onshape complete with the cutouts and latch release mechanism.

I haven't 3D printed this one yet because I ran out of filament, so I can't fully guarantee that it works as expected. However, when it's assembled in CAD in the assembly tab, it looks exceptionally promising.

The design can still be tweaked quite a bit more, but the one in onshape is much better than the Tinkercad one.

This essentially renders my previous post obsolete.

Here's the link for export and download. I think I set all the settings correctly. If I did something wrong, pls tell me: https://cad.onshape.com/documents/7ff07276d978bf63140884e3/w/fe9a9b18e05c0f1ebecf49cc/e/ab2e3b83565442349b529546?renderMode=0&uiState=67554b32ea294f114f0cd514

Update: I managed to print it with the limited amount of filament I had. It works well. There needed to be a couple tweaks made sure, but not much at all. I am satisfied with its performance. I'll make the changes tomorrow.

Update 2: I have finalized the design. I've modeled the new version of the latch release and it works much better than the old one. It should be under the tab "Newer Latch Bar". I can't see much room for improvement, so I'll leave it up to others to further improve it if they want.

If anyone is looking to install a Gotek USB floppy disk emulator into their Tektronix TDS500, TDS600, or TDS700 series scope, use this part number: SFR1M44-DU26
(Remove all jumpers EXCEPT J1)

You'll also maybe need an adapter bracket if you have the wider type floppy disk drive, so here it is:

And you'll also need an M2.5 x 10mm screw too.


(Pictures are of the 'real' part, but you can see how it'll end up anyway).

Bezel for 7000 series scopes. Won't fit all, but will fit most with standard CRT sizes ei 7904, 7613, 7633, 7623.

Not perfect, but it appears to work very well for me. Actual fabrication of the bezel may pose difficulties. Maybe have a 3rd party make them? The geometry of the bezel poses challenges when 3D printing.

Hi,
If it doesn't fit here, let me know and I'll delete it:

Hello,
I am looking for a suitable handle for my Hioki 3540.
The shape of the case and the handle receptacle look familiar, but I can't think of the right term to search for, at least I can't find anything.
Any ideas where I could get it from?

I took a screenshot of the handle receptacle and tried Google image search. It found the instrument you have, but no others it tried to match had the same star pattern. Maybe there aren't any others?

Hi, maybe if you give me the inner and out diameter of the hold I can quickly design one for you. Doesn't look too hard to make in CAD. I have already made a potential fit, just need the specific dimensions now.

I have attached a screenshot with drawings highlighting the dimensions I need.

If possible, providing the shell thickness will also be useful.

Dimensions in mm is preferred.

It's similar, though not the same, as the Solartron 7150. I can't imagine that Hioki wouldn't make their own cases, though I guess it's possible it was also sold under another brand name as well   


EDIT: A quick search shows they've sold Escort products under their own brand name

I made a replacement rotary switch standoff for the Fluke 720A and Fluke 750A, it probably fits other Fluke items too, this one is 20.8mm long.

Here I have some feet for the Tektronix 7000 series mainframes. I have included both polarities for the feet, right and left (or left and right depending on if you are looking from the front or back).

https://cad.onshape.com/documents/4b6617036525a66a77628146/w/d47c5d3eb3ce438621c60860/e/e9ec7d4b98e91859e3fa4788?renderMode=0&uiState=678a796afb0a3a3e9e515d4c

The design is to be refined but it currently works just fine with no issues.

Warning!: If you print this in PLA, ABS, or any non-high-friction material, it will not have the same amount of traction as the original feet. The original foot inserts were rubberized for better traction.
