Restoration of Lecroy WaveMaster / WavePro Front Bezel by 3D Printing

[mrcy22]

Does anyone have a source file with these labels?

Well well,

after ordering 2 piece on PCBWay.com using Mechatrommer's updated Front Bezel SDL  ... as I liked to have them in black O;)

Received them ALL as heavy sandwiched in one cartoon box:

- one part of the middle strap broken

- all middle strap as as heavy curved, finally all broke...

- Bezel as deformed not straight as original on table

- even one dummy plug side broken as very thick

IMHO the 3D model requires some modifications, so the middle strap gets not broken closed to the connection main frame parts.

Also asking/looking for a slim floppy adapter to hold w USB connector...

Look attached about the disaster..

you can ask pcbway later again to do support on the fragile overhang.. i cant get to editing the model yet as i'm doing other work.. when i can get back to it, i think i will redo in one go the model for msla printing tolerance. the model i published was for abs/pla filament 3d printer with 0.3mm nozzle tolerance. so its not a straight forward job. ymmv.

The shipping parcel was the issue, as order (2 bezel's and some adapters) sandwiched all in one thin parcel. The parcel itself was OK, but inside any deformation happened.
 
Using FreeCAD & tutorial, I could build  the solid 3D model using 0.01 tolerance. But to remove on the middle strap all this half holes  and made the middle strap straight 

As PCBway as JLCPCB has more plastic options to select (online ordering system looks as equal).

The RESIN Black I used, IMHO to fragile, so PC (polycarbonat) as also in black would be the better option but about 80EU's.

Today I finally received the front bezel I had JLCPCB 3D print for me in ABS (off white). It took a bit longer to receive it because Fedex tried to deliver twice, then loaded it onto the wrong truck which still counted as the third delivery attempt so they send it back to China. JLCPCB's helpdesk sorted things out though and re-shipped the package.

The front bezel I received is perfectly straight although I got the usual remarks that some areas are too thin. It does look very 3D printed though. The curves in the original bezel are smooth where the 3D printed one clearly shows steps. I had to make a few adjusts with a file. The hole for the power button was slightly too small and the left side didn't want to close up but the latter problem can be cause by the frame being bent a bit. The oscilloscope got banged up a bit at some point. The Lecroy badge also doesn't fit but that cracked into pieces when I tried to remove it. Such crappy plastic 

Still the result looks way better than it was with the original bezel that had cracked again after painstakingly glueing it together.



A huge thumbs up for Mechatrommer to make these 3D files available    Thank you very much!

What did it cost?
I always file the bottom of the opening on the right, even in the original frame, because it has unnecessary stress and a tendency to break because of this.
I reinforce the vertical column with clipped stapler staples where it tends to break. I just press them with the thin edge of the soldering iron tip into the plastic. This is working.

congratulation. iirc i created the model with abs/pla printing in mind 0.3mm nozzle, so i made clearance about 0.3mm or more on each fitting and holes. You mentioned power button doesnt fit means they printed it larger than it suppose to be. And visible steps layers means they are using classic abs/pla method.. about less than 2 years ago i purchased msla printer, its like earth and heaven difference compared to filament printing. 0.05mm layer height and about 0.1mm tolerance or better can be achieved.. the problem is, its small print dimension limit. my next plan is to redo the model for msla printer. To topup back the mass that i removed. This requires me to open and remeasure the original part and hence will take more time. Dont expect its going to be soon though.. due to busyness.. i believe the current model can be used for both filament and msla printing. Its just if printed with msla correctly, the part should be much loosen when assembled on the dso. Also would like to know the cost they charged for filament printing.. one other guy who ordered msla printing unfortunately got distorted printout, got charged eur100, so i guess its a good business for jlcpcb.

I paid US $88 including shipping. The bezel I got seems quite sturdy and it fits without needing to stretch it. But I'll need to see how it holds up long term.

As mentioned, like to remove the curved notches and lets deal with a local 3D print shop as claimed 50Eu as using PETG...

if this material wraps too, I cannot comment yet... as all printed 3D should be cooled dawn slowly

but shipping, getting it by car (30Km) is saver as shippers on some countries as

Nice job

As looking on the given white and my black, surfaces looks any different, as more flat...

only the pitta on middle strap..
