Picotuner stl

[F1CJN_alain]

I printed the Picotuner front face from the BATC stl file, months ago and it was fine.
I think now the BATC file has been changed (little hole near the power plug) but the two square holes for power and usb do not fit at all with my Pico rev3 board.
Where can I get the previous file ?

Firstly, I think you mean the back panel as there is no power on the front, just some LEDs.

Drawings for both versions are in the Wiki, you just need to use the correct one for your board and cad up a panel in your preferred 3D design package. There never was a 3D panel as such, it was a drilling template for the metal panel that comes with the case. It could be used as a panel but it might be too thick, at least compared to the aluminium. You can probably change that in the 3D slicer but thin plastic isn't very stiff. You could even 3D print the entire case - the 3D files are on the Hammond website.

I printed a drilling template for the prototype, which is on the Wik under the V1 files. It is not under the V3 files as it won't work with the final version. I suspect you have printed that V1 template as that has a hole for the LNB LED that moved to the front in V3. The spacing of the USB and ethernet was also improved.

I did not print a drilling template for the version 3 because I didn't build one. I think someone must have asked for one though as I have a zip file with a template inside, no idea if it fits because due to the cost of the tuners I didn't build one myself. The only difference is the LEDs.

Justin had some metal panels made, complete with logos etc.

EDIT - I did a search - viewtopic.php?f=2&t=9044 - this might be where you found a panel previously. I thought I had updated the Wiki.

EDIT2 - I think someone has deleted the link from the Wiki as this file is there but not linked any more. https://wiki.batc.org.uk/File:PicoBackPanelSTL.zip

EDIT3 - It is linked, it is just at the end of the line so not as obvious.

Hi Mike

First, sorry to make a confusion for the name back panel , because in my shack the back panel is in front of me !

There are two STL files in the BATC repository, the second one is ok for my rev3 board :
- https://wiki.batc.org.uk/images/c/c7/3D ... nelPad.zip
- https://wiki.batc.org.uk/File:PicoBackPanelSTL.zip

Thanks for the link

I have asked to the free Gemini AI to make a 3D model for the Pico front panel from a text description.
I asked for a compatible file with OpenScad.
- First copy the file,
- Copy the file into the free OpenScad 3D application,
- generate the image and export it as a STL file,
- print the 3D model with your prefered printer.

I put the front panel STL file and also the modified back panel STL without the Ethernet connector hole, in this repository

Interesting approach. Perhaps ask it to label the panel and countersink the holes?

Thanks it is done ans has a good shape.

That looks good, but I only meant the mounting holes. LEDs however don't look bad countersunk. Interesting.
