2, CAD new ideas, Power terminal enclosure:

Info:

After some thoughts about this I decided to built a separate box that holds the fuse terminal, ground terminal, main switch and the Volt and Ampere meter. Then I can change to other PCs without have to build a new enclosure.


New designed box for Power terminal:

After I had redone the drawings to my new ideas I came up with this. The later coming lid will hold the main switch and the Volt and Ampere meter. But one problem, the holes I have made doesn't come into place as they should. I found that the order of my drawings were wrong, the holes are better to have at the end. I tried to move the sketches but got the error message, "violate the dependences".

The look of the backside, several hexagon nut pockets.


Changing order of the holes of the sketch:

Before I start all over again I renamed the sketches and tried to use some tools to investigate the problem.


Scene Inspector:

There is a built in tool, the Scene Inspector, but I don't know how to use it yet.


Dependency Graph:

There is also an extra option to download a tool with the name Dependency Graph, It will draw a tree of all modules in the drawing. Couldn't get it to work, yet.

More information about the Dependency Graph:

I took away all pockets and holes, after that I could change the orders of the sketches. When a Sketch is marked, its view can be turned on or off with the space key.

Built it up with new Pads, Pockets and Holes. In some cases I have to change the reference position of the Sketch, it must connect at the correct distance on the Z-axis. Maybe other axis in your case, it depends on the orientation of the drawings. Here I have changed it from 0 to 6 mm, at the top surface of the XY-backplane.

Continue with the construction pins that shall hold the ground terminal in place. My first idea was to have holes and screws here.

These two pillars will go into the terminal block and hold it in correct position. The holes in the terminal block has a diameter of 3 mm, I set these two pillar's diameter to 2.8 mm.

After a while I got everything in place, there is no boring time here during the Corona. At top of the two distances the fuse terminal will sit.

With rounded edges and ready to be 3D-printed. Earlier I used the Pad tools to do this, but it must be better to use the Pad Design tools. Maybe one reason that I got so much problem earlier when I mixed up two different tools. Important, don't use to big radius, if there isn't space for it it will crash. Here I used: 1, 2, and 3 mm radius.

I setup the slicer to 1.5 thickness of walls, 30% infill and a brim around the bottom. It need 8 hours to print this box. I can see now when it's printing that the walls around the nut pockets are too thin, wall thickness of at least 2 mm had been better.
