The Prusa Core One works with any USB webcam that the 3DPrinterOS Client can detect, including the Logitech C270 and C920. The challenge is physical: the Core One enclosure has no built-in mounting point for third-party cameras, so getting a webcam in a useful position requires a custom 3D-printed mount.

This article covers the most popular community-made mounts for the C270 and C920, hardware notes for each camera, and what you need to know about software setup.

The Buddy3D Camera (sold by Prusa for the Core One) is not supported in 3DPrinterOS and will not be supported in the future. It is designed exclusively for use with Prusa Connect and the Prusa mobile app. Do not purchase it expecting compatibility with 3DPrinterOS.

The Logitech C270 and C920 (including C920x, C920s, C920e, and C930) are the most widely used webcams with Prusa printers. Both are detected automatically by the 3DPrinterOS Client when connected via USB.

There are no commercially available mounts for the Core One with these cameras. All solutions are DIY, printed on the printer itself. The designs below are the most popular Core One-specific mounts on Printables.

Prusa Core One Webcam Mount for Logitech C920/C930 by BlueFyre
The most liked Core One C920 mount on Printables. Corner-mount design using six 6x2mm magnets. Attaches in the upper corner of the enclosure frame in the same position as the Buddy3D camera. Requires partial camera disassembly following the iFixIt C920 disassembly guide (steps 1-5 only, removing the metal mounting arms). Cable routing can follow the Buddy3D installation path through the front frame hole. Note: the C920's USB-A plug and ferrite core are too large to fit through the standard Buddy Cam hole without frame modification; most users route the cable out a corner of the frame instead.

Alternative corner mount based on a remixed GoPro-style adapter. Same partial disassembly required. The filament holder hole on the Core One fits a USB-A plug but not the ferrite core; users without a Dremel typically route the cable out a frame corner.

Prusa Core One Camera Case/Corner Bracket for Logitech C270 by nielsvm
Installs in the upper-left corner of the enclosure, matching the Buddy3D camera position. Requires disassembling the original C270 plastic housing and reassembling the internals into the printed case. Use the Logitech C270 Magnetic Case as a reference for reassembly. Print in PETG or ASA; do not use PLA inside the enclosure due to heat. Uses magnets. Cable routing follows the Buddy3D guide.

Print all camera mounts in PETG or ASA. The Core One enclosure retains heat during printing, especially when running materials like ABS or ASA. PLA will soften under these conditions and the mount may sag or fail over time.

Plug the camera into the host device running the 3DPrinterOS Client (Raspberry Pi, Windows PC, or other supported platform). The Client detects USB cameras automatically. Once detected, go to Printer Settings in 3DPrinterOS Cloud, select the correct camera from the list, and click Save changes.
