3D Printing @ FirstBuild

The purpose of this repository is to store information about using 3D printing resources in the Louisville, KY FirstBuild Makerspace. The scripts below will automatically setup the FirstBuild printers on your machine running Bambu Studio or Orca Slicer (untested).

Installing Bambu Printers

These scripts install the certificate and printer definitions required to connect to the Bambu Lab printers in the FirstBuild makerspace.

Quick Install

Choose the instructions for your operating system:

macOS

Run this command in Terminal:

curl -fsSL https://raw.githubusercontent.com/FirstBuild/3D-Printing/main/Install-Bambuddy-Cert-MacOS.sh | bash

The script will automatically download the latest printer configuration file from GitHub.

Linux

Run this command in your terminal:

curl -fsSL https://raw.githubusercontent.com/FirstBuild/3D-Printing/main/Install-Bambuddy-Cert-Linux.sh | bash

The script will automatically download the latest printer configuration file from GitHub.

Windows

Three steps — no ZIP download needed:

1. Go to https://github.com/FirstBuild/3D-Printing and right-click on Install-BambuddyCert.bat and click Run as Administrator
2. Click the download button (the icon with a downward arrow, near the top-right of the file view) and save the file anywhere — your Desktop works great
3. Double-click the downloaded Install-BambuddyCert.bat file

A black Command Prompt window will open, download everything it needs from the internet, install the certificate, and configure the printers automatically. When it says "Done!", press any key to close it.

Tip: If Windows asks "Do you want to allow this app to make changes?", click Yes. If you see a blue SmartScreen warning, click More info then Run anyway.

Adding Printers to Bambu Studio

Once the script has been ran, re-open Bambu Studio and make sure you're connected to the Firstbuild_private WiFi network. The printers should automatically show up in Bambu Studio after a few minutes.

Staff-Only Printer Access Codes

Public printers can keep using plain access_code values. Staff-only printers can use encrypted codes instead.

JSON format

For staff printers, set:

• staff_only: true
• encrypted_access_code: "enc-v1:..."

The installer scripts support both formats:

• Public: access_code
• Staff: encrypted_access_code

If an encrypted staff code is present, the installer prompts once for a staff password. If no password is entered, staff-only printers are skipped and public printers are still configured.

Easy update workflow for staff codes

1. In bambuddy-printers.json, set staff_only: true on staff printers.
2. Update each staff printer's plain access_code to the new value.
3. Run:

python3 Protect-Staff-AccessCodes.py --file bambuddy-printers.json

4. Enter the staff encryption password when prompted.
5. The script replaces plain staff access_code values with encrypted_access_code.

Tip: use the same staff password expected by team members who run installer scripts.
