Raspberry Pi - Cyberdeck

 This was a fun personal project. I created a 3D printed case for a Raspberry Pi 5 and a 7” Raspberry Pi Touch Display 2 screen. The case was modeled in AutoCAD using solids and 3D printed on my Bambu Lab X1 Carbon printer. The back panel was modeled with keystone inserts so I can use various keystone jacks for the rear I/O. The rear I/O consists of ethernet, USB and HDMI. I currently have a 3D Printed mouse in matching colors and a small keyboard. My plans are to use it for motoring my Unifi home network lab, home automation and media streaming box. I also plan to create a miniature stop light setup and controller using Python and Scratch. Learning Python should be fun. Enjoy!

Stafford County, Va. Road Project 360 VR Animations

 Here are the two 360 degree VR animations I created for a Stafford County, Va. Road Project. The model was built with a land surveyed surface, Civil 3D corridors, pipe networks and so on. I then brought everything together in Autodesk Infraworks then Autodesk 3D Studio Max for a little cleanup. I then imported the model into Epic Twinmotion.

AutoCAD 2026!

 AutoCAD 2026 has hit the shelves. Time to play with the new features.

Intersection Animation

 Here is an intersection I'm working on. It's built with AutoCAD/Civil 3D. The flythrough is created with Epic Twinmotion. I hope to have buildings added soon.

3D Modeling in AutoCAD for 3D Printing

 Here is a short tutorial on 3D printing AutoCAD 3D models.

Christmas Ornaments

 I'm drawing and 3D printing Christmas ornaments. They were modeled in Autodesk AutoCAD and Fusion 360. I used the 0.2mm and 0.4mm hotend assemblies on my Bambu Lab X1 Carbon for printing.

Autodesk University 2023 3D Printed Chip

 I created an Autodesk University chip I plan to hand out during the week of AU. I used AutoCAD solids to create the model. As for the QR code, I converted the QR code image to DXF and cleaned it up in AutoCAD. I tested the QR code with my smartphone while in AutoCAD and then in the Bambu Lab Studio slicer software. It worked so now to 3D print the model and test the QR code. I used Numakers PLA filament in three colors. The QR code works but I feel it can be improved. More to come!

Here are a few updated 3D prints. I used a 0.2 mm print nozzle for better accuracy. The downfall, it took twice as long to print compared to using the 0.4mm print nozzle.

3D Printed Miniature Traffic Control Box

I created a miniature traffic control box for a co-worker who is into miniature LED stop lights. The box will house the electronic controllers for the LED stop lights. The model was created in AutoCAD 2024 with 3D Solids then exported to a stereolithography (STL) file for slicing in the Bambu Lab software. I used yellow Numakers PLA+ filament. Total print time was around 14.5 hours. I had to make a few adjustments to the print speed and temperature to use the Numakers PLA+ filament.

Autodesk University - AutoCAD & General Design

Thanks to Autodesk for featuring my class on the main AutoCAD & General Design page.

Bambu Lab 3D Printer

My Bambu Lab X1 Carbon 3D printer has arrived. I test printed the Benchy boat. Everything looks good and printed fast. I'm looking forward to printing my CAD models. Stay tuned!

XREFs on Layer

Over the years supporting AutoCAD/Civil 3D, I have been asked, where are my XREFs?  Co-workers have placed the references on the current layers and turned off that layer. I wrote a simple lisp routine that will place the reference on a specified called "G-ANNO-REFR" which can be changed to your company standards.

The lisp routine uses the "XA" command (which can be changed to your likings). XA is a default command for XATTACH. Once the lisp routine is set in the CUI startup, it will override the default "XA" command. Run the XA command to attach a drawing. Once the drawing is attached, the previous layer will be restored.

Items in red can be changed per user preference.

Cleanup the "Temp" folder!

Over time, the c:\Users\%USERNAME%\AppData\Local\Temp\ folder will collect Gigs and Gigs of files from software. It's best to clean it from time to time but make sure there is not anything useful in this folder before deleting. Once it's gone, it's gone. I am not responsible for anything that is deleted. You can navigate to the folder to manually delete the files and folders or create a batch file to delete the files and folder with just double click. I execute the file about once a month to clean the Temp folder.

Here are the steps to create the batch file.

1. Open Notepad.
2. Copy and paste the script below into the blank Notepad file.
3. Click File then SaveAs.
4. Click the "Save as type" pull down to select All Files. This will allow the Notepad file to have another file extension type.
5. Name the file to your preference with a .bat extension. I named the file "Delete User Temp Files.bat".
6. Execute the batch file. You'll see Command Prompt screen appear as it's deleting the files and folders. It will not delete files and folders that are currently being utilized by the OS or open software.
