Darcy (or anybody else who is interested)-
I got the SLA back from Shapeways, so it’s available if you still want it. Is anybody else interested in adding a light to your Davis Mk 15?

I took some measurements and was drawing this up when it occurred to me that the easiest way to make this is to have it 3-D printed out of clear or translucent plastic. That will save you from having to scrounge up the plastic & glue the pieces together. So I created the model on CAD and uploaded it to Shapeways and it would cost them $7.50 to print it up plus probably a few more to ship it. That’s probably about as much as if you went out & bought the plastic yourself. What you would have to do is trim it with a file (if it needs it) & paint it with model paint. Then you glue it onto the sextant with 5 min epoxy & add the Velcro patch for the little Photon LED light.
Does that sound like it might work? Here are the shots of the 3-D model. The black areas you paint first with white paint to make it reflective on the inside, then black paint on the outside. The red areas you keep unpainted
Sorry this took so long - I will sketch something up this weekend and send it to you.
