modify_stl_section

MCP tool from MCP 3D Printer Server by DMontgomery40

Apply a specific transformation to a selected section of an STL file. This allows for detailed modifications of specific parts of a model.

How to use it

modify_stl_section is exposed by the MCP 3D Printer Server MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the modify_stl_section tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.

Install MCP 3D Printer Server

$npm install -g mcp-3d-printer-server

Other tools in MCP 3D Printer Server (21)

cancel_print

Cancel the current print job.

center_model

Translate the model so the center of its bounding box is at the world origin (0,0,0).

check_fulu_orca_setup

Inspects the FULU OrcaSlicer-bambulab executable, platform runtime payload, setup commands, and optional BambuNetwork bridge probe.

confirm_temperatures

Confirm temperature settings in a G-code file.

extend_stl_base

Extend the base of an STL file by a specified amount.

fulu_bambu_network_rpc

Calls one FULU BambuNetwork bridge JSON RPC method. Read-only methods such as bridge.handshake, bridge.runtimeinfo, and net.getuserprintinfo are allowed by default. Methods that can mutate account, printer, cloud, or print state require allowmutatingmethod=true; FULU print methods also require bambu

generate_stl_visualization

Generate an SVG visualization of an STL file from multiple angles (front, side, top, and isometric views).

get_printer_status

Get the current status of the 3D printer.

get_stl_info

Get detailed information about an STL file, including dimensions, vertex count, and bounding box.

lay_flat

Attempt to identify the largest flat surface of the model (that isn't already facing directly up or down) and rotate the model so this face is oriented downwards on the XY plane (Z=0). Useful for orienting models for printing.

list_printer_files

List files available on the printer.

merge_vertices

Merge vertices that are closer than a specified tolerance. Helps close small gaps and can slightly simplify the mesh.

print_3mf

Uploads a sliced .3mf file to a Bambu printer via FTP and initiates the print job via an MQTT command. If the 3MF has no embedded plate G-code and a project slicer is configured, the server can auto-slice it first with FULU OrcaSlicer-bambulab or Bambu Studio. Allows overriding some print parameters

process_and_print_stl

Process an STL file (extend base), slice it, confirm temperatures, and start printing.

rotate_stl

Rotate an STL model around specific axes (in degrees).

scale_stl

Scale an STL model uniformly or along specific axes.

set_printer_temperature

Set the temperature of a printer component.

slice_stl

Slice an STL file to generate G-code.

start_print

Start printing a file that is already on the printer.
