I have been using my old simple wedge design in my firefigher job but it rarely got used because of one big problem. Most often we have large gloves on and with the old wedge attached to my turnout gear with a carabiner it was a struggle to get of.

This wedge solves that problem by having a quick release function where you can just pull it from the holder.

I got the inspiration for this design from this Door wedge by ProSMP. So the idea is that this can be placed under the door, on the top of the door, on the side of the door or just over the hinge. The possibilities are endless. Have a look at the model pictures for some ideas.

For this to work as intended the wedge have to be printed from TPU 95A and the rest in PLA or preferably PETG. The print profile has infill and wall count optimized to have the right amount of flexibility. You only need one plate of the “Hard parts”, there is one plain and one with an example on how to add text, like this:

Update 2026-03-18

Added a large version of the wedge that better suits thicker doors like exterior and security doors. The only difference is the actual wedge, they both use the same quick release and inner part.

Assembly instructions

The assembly is quick and easy but here is a few steps.

1. Press the inner part into the wedge from the bottom till it clicks into place. This might take some force.
    

2. Add a key ring or something similar that can be used to attach it to your turnout gear or where ever you want it.

   

3. The holder clicks onto the wedge and is ready to be used.
