Print your own cases, part 4 of 10

In my previous post I created a round container for my electronic thermometer and now I need to add it to my Poser model. But I also need a special stand for Anarani to stand upon, with a back panel for a couple of magnets. Lets immediately start with the OpenSCAD script:

$fn=250;
difference(){
  union(){
    cube([60, 60, 6]); 
    translate([28, 0, 0]) cube([4, 3, 160]);
    translate([20, 1, 10]) cube([20, 2, 20]);
    translate([10, 1, 140]) cube([40, 2, 20]);
    translate([30, 1, 20]) rotate([90, 0, 0]) cylinder(d=12, h=1);
    translate([20, 1, 151]) rotate([90, 0, 0]) cylinder(d=12, h=1);
    translate([40, 1, 151]) rotate([90, 0, 0]) cylinder(d=12, h=1);
  }
  union(){
    translate([3, 3, 2]) cube([54, 54, 5]);
    translate([30, 1, 20]) rotate([90, 0, 0]) cylinder(d=10, h=2);
    translate([20, 1, 151]) rotate([90, 0, 0]) cylinder(d=10, h=2);
    translate([40, 1, 151]) rotate([90, 0, 0]) cylinder(d=10, h=2);
    translate([30, 2, 150])
    rotate([270, 180, 0]) height = 2) {
      text("Anarani", 
      size = 7, 
      font = "Harlow Solid Italic", 
      halign = "center", 
      valign = "center"
      );
    }
  }
}

This isn’t very special. A floor plate with an edge and a pole with two plates which will hold the magnets. As you may notice, there is no connection to the box that I created in the earlier post. That connector will be something from Poser. All you have to do now is to convert these models to WaveFront .obj files and you can import them in Poser. So, let’s combine them with Anarani! And this will show a few issues with importing in Poser.

When you do import models in Poser, prefer to enable “Percent of standard figure size”. The reason for this is that the standard figure size is extremely small, compared to the imported objects. I will scale them anyways once they are imported and because their size is relative to Anarani, I can use integer values between 1 and 100 to scale them. Otherwise, I would need to scale them to very small numbers with fractions.Anarani for blogpost II_0001

Now, to do a proper scaling, I will use the ruler to measure the height of the opening in the temperature holder, which should be 46 mm. I will then use the ruler to scale the back panel to the proper size, thus having it synchronized with the size of the box.

You could wonder why I don’t combine all three parts into one .obj file and import that one, but when I do that, it becomes just a single part. And I need to move them around, so that isn’t very practical.

So I end up with my model looking like the image on the right. The temperature box is too big and the ruler is extremely small. The back panel seems to be okay, though. But first I will have to put Anarani in a nice pose. And reconsider the clothing she’s wearing, since not all clothes will print well on Shapeways. (Hint: if a piece of clothing is transparent when you look at it from a specific angle in Poser then it will not print very well!)

The next step is trying to make everything fit. Since the box is quite large, I decide that Anarani will hold it above her head, thus making the model even taller. I don’t want it to go in all three directions because that would require more machine space, thus making it more costly. The final height will be about 22 cm and it’s 75 mm wide and about 60 mm deep. (The sizes are from the bottom panel and the box.) The ruler is set up vertically so I can use that to scale it to the proper length, which would be 60 cm. I will then cut away the ruler from the model and thus have the exact height, although I don’t think the width and depth will change much from my prediction.

Anarani for blogpost III_0001Anarani will look like this image. One foot on the floor panel and a second one against the back panel. Both feet touch these panels so they should be connected, although the support will be tricky.

The ruler has moved towards the back and will be used in one of the next steps to set the proper scale of the model, before I will remove it.

The box itself is held up by her arms. Here, the hands will need to touch the box to make sure that connection is strong too. But they can’t connect too well, else the fingers will disappear.

To get things at the proper size, I started with matching the ruler to the length of the back panel, which was 16 cm. I then used this to scale the box so the vertical height of the opening is 46 mm. If I did the math well, my device should fit just nicely.

I have given Anarani high heels to wear and replaced her top with a bikini. This bikini top has a clothing thickness property allowing me to set the thickness of it, thus making sure it prints better.Anarani for blogpost IV_0001

The skirt she’s wearing is also special, since it is one of the few skirt models I have that has both an inside and an outside. Most clothing props for Poser tend to just cover one side and the render engine is smart enough to come up with the other side, if it needs to be rendered. But when you want to print those props, then the thickness is unknown and the repair function of Shapeways will actually fill it all up, thus turning the inside of a skirt into a massive block. With this skirt, I still have a skirt that you can look under.

I won’t tell if she’s wearing a bikini bottom!

As an extra support for the box I used a cane prop from Poser and put it to the proper scale and thickness. It should add stability to the whole thing. making sure the bottom plate doesn’t bend over due to the weight of it all. Since there will be magnets on the back side, that bottom plate would not be supported and thus bend. This cane also required me to make Anarani bend slightly. After I put the hands in placed and locked their place, I moved her hip to the side and started to bend back her abdomen and chest to go near the cane again. Next, her neck was bent away from the cane and her head back to the cane so her neck and head (and hair, ear) would not touch the cane.

To make sure it is well-balanced, the whole box is in the center of the floor panel so it doesn’t matter that Anarani is leaning on her left foot. Gravity works downwards so the model won’t tilt to the left or right. Also, the border on top of the floor plane was added to make it stronger without making it much thicker.

I used a cane because the box is higher than the back panel. The cane adds a few more cm to this height. Add to this the height of the box (50 mm) and you get close to my estimation of 22 cm in total.

In my next post I will render the model in Vue, with some interesting textures, just to show what it will look like.
