Automated heat-set threaded inserts using printer nozzle (post-print operation)

I would like to propose a new feature for Bambu Studio that enables automated installation of heat-set metal threaded inserts using the printers hotend after the print is finished. Heat-set threaded inserts (M3, M4, M5, etc.) are commonly used in 3D-printed parts to create strong, reusable threads. Today this process is typically done manually using a soldering iron. However, the printer already has everything required to perform this operation precisely.

I have successfully tested this concept manually by using the printer nozzle to heat and press inserts into a finished PLA print, and it works very reliably.

Proposed workflow:

1. Add a new tool/icon in Prepare to mark locations for threaded inserts
2. User selects one or more holes/positions on the model placed on the plate
3. For each insert, user can configure:

• insert type (e.g. M3/M4/M5)
• nozzle temperature (e.g. 220C)
• heating dwell time (e.g. 5-10 seconds)
• insertion depth
• insertion speed

After the print finishes (post-print operation):

1. Printer moves to a safe parking position and moves the bed forward
2. Printer pauses and prompts the user to manually place metal inserts into the marked holes
3. After resume:

• the nozzle heats up to the configured temperature
• moves to each insert position
• touches the metal insert to transfer heat
• slowly presses the insert to the configured depth
• retracts and moves to the next insert

4. After all inserts are installed, the printer performs the normal end-of-print procedure

I will attach a short video demonstrating the real printer-side workflow, which shows how reliable and repeatable this process already is when done manually. This is currently a feature proposal, so before implementing anything, I would like to collect feedback from other users who regularly use heat-set inserts or anyone who sees potential issues or improvements with this approach ;-)

Good idea, provided that your inserts are always at the top side top layer of the print.
