3D printed dremel attachments for guitar binding.

Recommended Posts

I'm re-working a guitar that I built a couple of years ago.  I have glue'd a really nice piece of flame maple veneer to it using a vacuum bag that I made from scrap at our engineered films division and I have put binding on it in order to hide that it is a veneer top and to protect the edge.  I decided to print some of the tooling for doing this.  I made 2 dremel attachments.  One of them for cutting the binding channel on the edge of the guitar and another for trimming some ABS strips into thin pieces for additional decorative strips on the edge of the binding (called purfing).

I have not taken pictures of the attachments themselves but I do have screenshots along with solidworks models of the parts/assemblies.

Printing the parts probably saved me from buying around $150 worth of tooling to do this.

Here is a cross section of the binding trimmer with the dremel router bit highlighted blue.  The binding passes through the little slot to the left of the bit where I trim it a bit at a time by adjusting a screw.  A spring loaded piece maintains pressure to keep the binding piece against the adjustment guide.

And an isometric view.  The top piece attaches to the dremel and is clamped in place.  I have an extra part in there because it is based on my binding channel cutter where I added another threaded portion for depth adjustment once the tool was attached to the dremel.

And for fun, here's the guitar in process.  It has the first coat of dye that will get sanded back to leave the dye in the deeper figure then I'll put a lighter green/blue dye on to get a nice color combo and really make the figure pop.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
