Mark,? thanks for the response.

I put the main PCB in the box and it is a tight fit. So much so, that the PCB does not need screws or the nuts for the BNC or the three 1/8 inch jacks to secure the PCB.

In other words, it ain¡¯t going no where once installed.

I had? to open up the BNC hole and cut away some of the opening where the PI USB / Ethernet connectors are so the PI could clear. Not a lot of material, just a fraction.

This box was printed with PLA and that might be some of? the problem with dimensional accuracy, but I don¡¯t rightfully know.

Yes. The ribbon connector locking mechanism is not very strong and will snap in half easily. Been there, done that before.

I ordered those ribbon cables. Like you, I will have more then I need.

To open up that channel for the display, I tried cutting a deeper channel with my Dremel but it was rough. Later, I found that using a large head nail in my ¡°el cheap O¡± ?soldering iron, allowed me to melt? a groove.

Barry,

wish I could say I was surprised that the display channel was not correct. One of the things that 3d printer owners struggle with is dimensional accuracy. ?This is a function of flow rate of the materials as well as real steps in a given dimension. And of course it gets worse with larger pieces as errors add up. ?Hope making it fit wasn¡¯t too much work! ?I made it a tight fit on ¡°my machine¡± ??


I did buy ?and use longer cables. Someone had ?in a prior discussion provided a pointer to an assortment of cables on Amazon and I just ordered them. ?This is what I ordered

Now I have more cables then I know what to do with!

and of course be gentle with that connector on the pi4 board ?broke the retainer in mine:-( ?but was able to transplant the camera connector to replace it ?
