Q:

Are there easier ways to make traps than coax and plastic pipe?

I recently built an antenna for my attic inspired by http://degood.org/coaxtrap/. I found making the coax traps very time consuming and frustrating to tune. 
I got to thinking about 3D printers, and I've been wondering if there is a better option (at the very least using a 3D printed form instead of PVC pipe.) With modern construction capabilities like CNC mills and 3D printers, not to mention inexpensive high quality circuit board production available, are there any better choices these days?

A:

W6NBC had an article published in QST in February 2011. 
Here's a link to it
He details creating traps without forms, and they certainly look easier (once you got the technique down anyway) to build.
He summarizes four key points that make them advantageous:

Easier to make with a whole number of turns
Lighter in weight
Lower in Cost
Simpler fabrication
