Flexi Cat Door – Print-in-Place

Flexi Cat Door – Print-in-Place or Pin-Assembled Pet Access Door

Give your feline friend the freedom they deserve with the Flexi Cat Door – a 3D-printable, low-profile pet door designed for ease of use and versatile installation.

This clever design offers two build options:

- Print-in-place for a fully integrated, no-hardware-needed hinge (ideal for fast, single-print setups) - Assemble with two 2mm brass pins for a smoother, more durable swing action No matter how you print it, the door frame is secured using four BT2.6x8 screws , holding the front and back halves firmly in place on most interior doors or panels.

Features:

- Works for most standard door thicknesses - Lightweight yet durable flexi hinge design - Cat-sized flap with just the right tension for easy entry and exit - Clean, modern look that prints well in PLA, PETG, or ABS Perfect for litter box closets, basement access, or keeping food bowls safe from dogs — the Flexi Cat Door is a quick, functional print that keeps everyone happy.
