SCP,

the emblem representing the fictional organization tasked with securing, containing, and protecting anomalous objects. The circular design, marked by three arrows pointing toward a central point, symbolizes order, control, and the convergence of knowledge.

Dimensions:

Diameter of Logo: 6cm / 2.36in
Thickness: 7mm / 0.28in

Diameter of Keychain hole: 4.6mm / 0.18in

I recommend printing with at least a 0.4 mm nozzle and a 0.2 mm layer height. For better results, higher print quality will increase the quality more.

If you have any questions about the size or thickness, or if you’d like any changes, feel free to contact me.
