Ozempic For Doors
by KlooDoh
Ozempic For Doors changes the hitboxes of open doors and trapdoors so players can slip through tight gaps without catching on the frame.
What it does
Open doors and trapdoors get a one-pixel hitbox on the hinge side, which makes movement through narrow spaces easier. In vanilla, an open door can snag a sprinting player on its frame; with this mod the door swings past the frame and lets the player through cleanly. Closed doors and trapdoors keep their original collision, so a base, a redstone contraption or a mob-proofing setup behaves as it did before the mod was added.
The change also reaches block spaces that include doors, trapdoors, cauldrons and composters. Installation covers the server and each player's game. Files are published for Fabric and NeoForge for 1.21.10 – 1.21.11. The code is all rights reserved, and the mod is not open source.
Key features
Open door hitboxes
Open doors and trapdoors gain a hinge-side hitbox one pixel thick, so passing them is less likely to catch.
Closed doors unchanged
Closed doors and trapdoors keep their vanilla collision, leaving redstone builds and mob-proofing as they were.
Matched outlines
Selection boxes and collision shapes are applied to existing doors and trapdoors so the visuals match the actual hitbox.
Cramped spaces
Tight corridors, decorative door frames and compact redstone hallways become easier to move through without bumping the head.

How it compares
Chaotic Tweaks is server-side only, released under the MIT License and published for 1.21.10. Milk in Cauldron is client-side only, open source under the Apache License 2.0 and covers 1.21.9 – 1.21.11. Dispensive Cauldrons is server-side only, released under the Creative Commons Attribution 4.0 license and covers 1.21.10 – 1.21.11, so it works with cauldrons rather than door hitboxes.
