I created an easel using 123D Design, made for 3D printing. You can see it in the 3d viewer below and in the picture.
Step 1: Concept Design
My concept was to make a series of "blades" with a notch cut out that would act as an easel.
Step 2: Make the Segments of the Stand
Here's how I made them:
- Add a sphere into the scene, with a radius of 10mm
- Add a box into the scene with dimensions of 40x40x10mm
- Line them up so that the top half of the sphere sticks up above the box
- Select the Combine icon on the toolbar
- Select the sphere as the target
- Select the box as the additional primitive to combine
- In the little pillbox menu, at the end, select Subtract
- Press Enter
- Voila, half sphere!
- Select the half-sphere and then the Transform icon, then the Move icon
- Move it down so it is touching the ground plane
- Now select the Transform icon from the toolbar, and then the Scale icon
- In the little pill, select Non-Uniform scaling
- Adjust the size in each dimension - maybe 6x taller, 2x wider, 4x deeper
Step 3: Cut Out the Notch
- Make a box 40mm wide x 60mm tall x 7mm deep.
- Select the box and move it so that it overlaps the blade - you might want to use the side view while doing this. Select it by clicking on the view cube in the top right
- Tilt it backwards, about 10 degrees, using the Transform icon
- We want the notch to be angled forward too, so grab the Tweak icon from the toolbar, and now select the top forward edge of the box, and pull it forward
- Looks good!
- Select Combine from the toolbar
- Select the blade as the target, and the box as the primitives to combine. Select subtract from the pill menu. Enter!
- You can give a nice curve to the edges of the notch by using the Fillet tool - select it from the toolbar, and then edges of the notch.
Step 4: Copy the Shapes
Select the first one, and copy it by typing Command-C or Ctrl-C. Now type Command-V or Ctrl-V to paste it. You'll see the arrows for moving appear. Slide the blade over, about 20mm. It should snap to the grid.
Do this again, 3 more times, for a total of 5 blades.
Step 5: Join Them Together
- Add a cylinder from the toolbar - make it 100mm x 10mm radius.
- Using the Transform icon, turn it on its side
- Make a box just bigger than the cylinder, 10mm high
- Just like we did with the sphere at the beginning, subtract the box from the cylinder to leave a half cylinder
- Move the cylinder down to the ground plane, and slide it forward so that it overlaps the blades
- Use the Combine tool again, this time to Join everything together
- Select the cylinder first as the target
- Select the blades as the primitives to combine
- In the pill menu, select Join as the action
Step 6: Print It
Use the software that came with your 3D printer to prepare it for printing. This model prints well with very sparse infill and a high number of shells.
When it is done, put your hologram in it, and enjoy!
