When I am not designing and 3D printing, I am often doing work that frequently leaves me wanting to have a doorstop or door wedge with me. And, I have thought about it a lot – I wanted to make one! I wanted to create something novel, functional and convenient. This is what I came up with… a fold-flat door stop that I can keep in my pocket or tool kit.
This 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° angle) and stand it up under a door. Pull the door onto it and voila! The door is stopped.
I used a 15° 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.
Printing
This product was designed for a 0.4mm nozzle, a 0.2mm layer height and the following settings:
Material: I choose to use PETG for its durability and flexibility
Wall Line Count = 4 ( 4 x 0.4mm = 1.6mm walls )
Top and Bottom Layer Count = 5 ( 5 x 0.2mm = 1.0mm top and bottom )
Infill = 100% for maximum strength (minimum 40%, Cubic)
Ironing = OFF (not needed)
Support = No support required
Brim = NO (If you have to use a brim, set it to “outside only”)
Material = PETG recommended (any material should work fine)
Print Orientation: As shown below.
Assembly Notes
No assembly or post-print processing is required.
