Project Description
General context for this project and a list of initial hardware requirements are in Ground Control Station Integration 2025.
The mechanical team is responsible for organizing the layout of the monitor, keyboard, ports, etc. The control system will be built into a Nanuk 930 case. Some components may need to be manufactured, such as mounts for switches, ports, lights…

Built into Nanuk 930 case | Smile | |
Fit a 6S battery or a few? | Daniel | |
supports ground station arch as outlined in the 2025 doc | Daniel | |
Use the 19” monitor that has been disassembled. It should be mounted in the top of the case as far back as possible to leave room for components on the bottom half when closed. Allow the VGA and Power cables to exit the top and enter the bottom half of the case. Make it look nice, cover the space around the monitor with polycarbonate. | Nathan Green | 2024-09-10 |

Task Progression/Updates
Calum: @ 2024/07/10
Created CAD model of Nanuk 930 Case based on website dimensions. The dimensions are quite vague and this is a rough idea to work off off.
Created plates from given drawings that will attach to the bottom and top of the case with #6 X 1/2" Hi-Lo Self-Tapping Sheet Metal Screws (18pcs) per plate. The case has premade threads.

Would like to know the dimensions and sizing of components so I can CAD them out and arrange them

Calum: @ 2024/09/20
Updated the cad to accommodate the new monitor sizing. This involved changing the spacer height, size of the top plate cut and changing the cut that each of corners had.
Updated all the parts so they have M3 holes for mounting, the top bezel plate has 1/8 inch self tapping screws that can be found in McMaster Carr: Phillips Rounded Head Screws for Sheet Metal, 18-8 Stainless Steel, Number 6 Size, 1/2" Long | McMaster-Carr (Still need to add the screws to the assembly)
Creating the top plate from MDMF in the rapid prototyping shop at waterloo
Will need to create 1/4 of the corners with a 3d printer to test if it will fit into the case
Still need to add all the spacers in the assembly since the new monitor sizing required changes to their dimensions
How the design works:
Corners will be 3D printed and placed into the case. Hopefully the corners will fit snug into the case and will prevent the monitor from rotating in the y-axis & z-axis. The corners will have holes that are concentric to the cases
the monitor will be placed into the case and will sit on the corners

UPDATE TITLE
...
Spacers will be screw into the top plate, Then the top plate (in blue) will then press against the monitor via spacers and provide force clamping it in the x-axis
Calum @ 2024 Sept 26
All corners have been printed and placed in the case. The monitor fits snug in the case with the corners and prevent rotation.
The spacers are waiting to be printed. (how deep should the M3 holes be?
The top plate has been updated and is waiting to be laser cut buy the RPC

Design review (moving over from the old ‘Monitor Mount’ doc
Make a prototype using particle board at RPC - Callum
The top plate is 18.42” x 13.47”, can’t be water jet in E5. Can be laser cut at RPC, or water jet in E3 EMS.
Material selection up to Callum. Acrylic or aluminum.
Spacer should be a separate part. Maybe 3D printed, and use a heat set to fasten to top plate.
make out of hole wizard and use normal screw clearance.
...
Make holes with hole wizard. Holes should be normal screw clearance.
Idea: could cut out a groove in the corner piece that the bezel slides so that a top plate is not necessary
Calum @ 2024 Oct 8th
Ran little FEA simulation on the top plate with Smile The max stresses seem to be 2.307MPA
The yield stress of Acrylic is: Tensile Strength, Yield (64.8 - 83.4 MPa)
According to this simulation the top plate should be able to hold the monitor
Calum Chisholm 2024 Oct 10th
Acrylic plate has been laser cut. Due to the laser? the hole cutouts are slightly too tight and it may not be easy to screw to the case
Talking with Smile Khatri he suggested that we used a drill to ream the holes making them bigger.
The bottom half spacers also had to be reprinted because the monitor is not completely flat. I made them 3mm shorter.
Plans for the future: Would like to paint the top plate black and in the future integrate the spacers into the corners so they are uniform piece.
