Designed with a generous 40 mm size, this cube makes every edge and recessed dot easy to locate by touch.

I once saw my wife in tears after our cat went missing — again. He’s an indoor cat, not used to the outside world, and every time he sneaks out through a gap in the gate, it turns into hours of stress and worry. That’s what motivated me to take action. I designed a custom 3D-printed gate barrier clip, made with brown PLA, specifically to prevent small pets — especially curious cats — from slipping through the gaps in gates or fences.
