This is a handy and innovative fold-flat door stop that I can keep in your pocket, drawer, tool kit or just about anywhere.

This print-in-place folding wedge operates in two ways allowing it to accommodate an under-door gap from 8mm to 60mm. It is thin, light and strong making it ideal for any handyman or tradesperson who needs a door wedge with them.

It is a print-in-place design that requires nothing after printing. Simply take it off the build plate and put it to use. Simply fold the two sides together (they are limited to 100-degree angle) and stand it up under a door. Pull the door onto it and the door is stopped.

I used a 15-degree angle for the stop which creates a fairly low rise making it easy to wedge under doors. But that slow rise means one side does not cover a very large range - only 8mm to 35mm. So I made it two-sided allowing the second side to carry on with an additional range for holding more doors - 33mm to 60mm.

100% printed - no hardware, fasteners, or adhesives required. No additional support is required.

Print Settings:

Material = I recommend TPU or PETG but any material should work.
Nozzle = 0.4mm Layer height = 0.2mm Line width = 0.4mm Wall count = 4 (1.6mm) Top and Bottom Layer Count = 5 Infill = 100%, minimum 40% Cubic Ironing = Not required Brim = No Support = No

2026-04-21: Posted a slightly revised version that will print in TPU in addition to other materials. TPU, if printed cleanly, gives this door wedge a little more flex and compression which is ideal for a door wedge. If you try it with TPU please let me know how it works for you.
