I’ve always found these double ring holders to be quite useless because the rings are too large and it’s easy to miss both rings when trying to insert a tool. So I created the Pegboard Double Ring Insert and posted it to Thingiverse. The model and openSCAD code is based on Pegboard hex driver adaptor thing #1727845 by CyFire.
Since I’m trying to only post high quality 3D models on this site I needed to clean up this project and make some improvements. First off I’ve added the ability to create space for a hex bolster.
I’ve also fixed the chamfer on the top of the holder so that it actually works. The chamfer helps direct the tip of the screwdriver into the hole and just gives the holder a more polished appearance.
Since there are so many different style pegboard double rings holders with different wire thicknesses, different hole sizes, and different ring distances, and they don’t even sell the same double ring holder I have anymore, it really doesn’t make sense to post a lot of STL files that probably wont work for most people.
Still I will provide a few example STL files that you can download and view to get an idea of what the model can do.
If you need instructions on how to customize a openSCAD model check out this page where I walk through using the customizer inside of openSCAD to create a custom socket holder. there’s no editing code, I promise, just changing some values in a text box.
Printer: Prusa i3 MK3
Slicer: Cura Slicer
Material: Inland PET-G
Resolution: 0.2mm with a 0.4mm nozzle
Wall Lines/Perimeters: 2
Infill: 10% Gyroid
Notes: These are a pretty fast print — about 30 minutes per holder
Chances are the STL files I uploaded aren’t going to fit in your double ring holder. You need to customize and create your own STL files from the openSCAD model.
These are the most important dimensions you will probably have to change to fit your particular double ring holder:
- The outer diameter of the holder (outer_dia), this is actually the inner diameter of the rings
- The the height of the holder (height) which is the distance between the top of the top ring and the bottom of the bottom ring.
These dimensions aren’t going to be exactly the same for each set of rings, because these aren’t exactly precision made. They are going to vary, but you can use a pliers to slightly open or close a ring if it is the wrong size and change the distances between the rings. I even had some cases where the rings weren’t in line with one another and had to tweak them quite a bit with pliers.
The 4 balls on the end of the holder and the lip are what hold the ring insert in place. There should be enough give in the rings for the end with the balls to pass though. Once through, the insert should stay in place. If it isn’t check to make sure you didn’t deform or shear off the balls, you can adjust the size of the balls to make it fit more securely.
