BASE CUBE Design Files

These files were generated using Autodesk Inventor 2019 Student Version.

To start working on it, you have to do the following steps:

1. Download the Assembly_Cube_3DP_v3.zip and unzip it
2. Open Inventor and import existing project
3. Select filename Assembly_Cube_empty_1x1_withBase_v3.ipj
4. Then open the assembly Assembly_Cube_empty_1x1_withBase_v3.iam in Inventor
5. The base-cube has two components: 10_Lid_1x1_v3.ipt and 10_Cube_1x1_v3.ipt which can be modified to personal needs.
6. The Baseplate puzzle 10_Base_puzzle_v3.ipt is also in this assembly and can be modified.
7. If you have a cool improvement for this part, please let us know! (CONTRIBUTING)

Screenshot of the cube in Inventor:

Alternatively the cube can also be used in the free (educational purposes) CAD software Autodesk Fusion 360 by first importing all components:

and then opening the .iam-file.

All the original design files as well as all the STL files can be found is CAD/RAW.

Tutorial on how to design an insert in Inventor

Note: The video and image tutorial both show a UC2_v2 Cube. Check the dimensions in the Modular Developer kit to make sure your part is compatible with the v3 Cube. However, the designing process is the same, no matter the version.

This is an example of designing an insert for any function you like. We are eager to see your results! Feel free to file a pull-request or share it via mail or @openUC2 on Twitter .

Video Tutorial on How to design a Cube Insert (Perpendicular to the optical axis)

1. Open Autodesk Inventor 2019 (Student) and open the UC2 project

2. Create a new Assembly

3. Place the UC2 base cube

4. Select the file. and pPlace the UC2 base cube

5. Ground the cube so that this is the reference for the insert

6. Create a new part which should hold a mirror

7. Give it a name and save everything

8. Select a reference plane for the new part to start a drawing

9. Start the drawing

10. Start the drawing II

11. Select the reference plane for the drawing

12. Derive the CAD-Drawings from the base cube

13. Have a look at the reference design for the cube insert

We want to design an insert which basically fits inside the cube. Thus, it has to be 53.8mm in diagonal and 6.28mmat the edges as shown below:

14. Create a rectangular sketch

15. Create a rectangular sketch

The dimensions are derived from the CAD-drawing in 13.

16. Add some support to make it 'slidable'

This is exemplary. You can add any shape you want as long as you can slide it inside the cube and keep dimensions in step 13 in your mind.

17. Extrude the sketch

It can be any value so that the part fits inside the cube. It has to be less than 32mmthough (see step 13.)

18. Look up the external devices Parameters (CAD Dimensions)

Here we review a Thorlabs silver mirror with 1 inch in diameter and 6mm in thickness

19. Create a sketch which represents a hole for the Thorlabs mirror

20. Extrude the hole so that a mirror fits in there

Add some imprecision boundary (e.g. .1-.2 mm)

21. Create a rectangular sketch

22. You're done! :)

Add any modifications to your design to make it work and share it - please! :-) @openUC2 on Twitter and as a github pull request :-)
