I made this wrench for my wife to use on milk jug lids and Arizona Tea jugs.
It is completely customizable so you can make any specialty wrench you need, such as water bottles, RO filters, etc.
Features
- Double ended wrench
- Single ended wrench
- Custom shaped teeth
- Triangle
- Square
- Trapezoid
- Add a hook hole for hanging
- Add a single or double magnet mount
Usage Notes
To make a wrench end, you need to:
- Measure the outside diameter of the lid.
- Count the number of teeth.
- Determine the height and shape of the teeth (as best you can; close usually works).
- You may use the Test option to make a trial fit – it may take several to get it right.
- To start, I suggest the beginning diameter to enter is what you measured plus the height of a tooth.
The handle:
- Any length, width, and height you want.
- Set the taper or filet amount between the handle and wrench ends.
- Add 1 or 2 holes for round magnets.
- If you want to wrench to hang slightly away from the metal (to grip it easier), set the magnet height less than the magnet so it will stick out.
- To get a snug fit, enter the magnet’s actual diameter, then add a small clearance (I suggest starting with 0.1mm).
- {Update} Cut out a slot shaped hole.
Using OpenSCAD and the Customizer
If you are new to using OpenSCAD and changing parameters, I’ve included my tutorial that may help.
I’ve included my settings so you can see examples of my wrenches. If you want to use it, here’s the steps:
- The settings file is a “.json” file (as required by OpenSCAD).
- Prusa does not allow this type of file to be uploaded.
- I have added “.txt” to the end to make it a text file for upload.
- You need to rename it by deleting “.txt” from the end. (You safely may ignore any warning about making the file unusable.)
- Place it in the same folder that you put the Custom Wrench.scad file.
Update Sep 6, 2024
The “Propel” settings were wrong. I replaced the .STL and the .JSON settings file. I also added a .3MF for the Propel/water bottle wrench.
Update Nov 6, 2024
Added an option to cut a slot style hole in the handle. Updated the .JSON settings file. Merged in other remixes and settings.
