Portable Monitor Secondary Screen Mount - VESA

A bespoke, portable monitor stand designed for use as a secondary display, connecting to the host monitor's VESA mount, generally compatible with most main screens and various portable monitor sizes. Two mounting orientations are supported: the portable monitor above or below the main screen

To accommodate diverse mounting configurations and screen dimensions, the print configuration includes two differently sized brackets

In addition to the printed parts, two screw sizes are required: M4x10 for connection to the VESA mount, and M3x8 for inter-bracket attachment, along with several M3 nuts

This project draws inspiration and modifications from numerous open-source projects on MakerWorld

The secondary monitor bracket component is adapted from Lukas - MakerWorld

The robotic arm component is derived from Multifunction Arm mounting system by rostap - MakerWorld

The nut sticker is adapted from wall-mounted nut sticker by Lyiang - MakerWorld
