So, I've been saving up for a used Ibanez SR505 5-string bass, and ended up getting an insanely good deal on a brand new SR655 instead.

I also picked up a pretty inexpensive case from Musician's Fiend (yes, a story for a different day), and the case is big enough, but has just a bit too much room.

So I learned that there was a free online near knock-off of SolidWorks 3D CAD software at www.onshape.com and saw that it allowed image import and scaling.

Printed out some graph paper with 0.25" squares, laid the new bass on the paper and snapped a picture which I imported into OnShape.

Then I proceeded to measure out some of the case dimensions relative to the bass and drafted some spacers that I will now cut out of 2x4 at our library (yes, our library has a maker-space and it's awesome).

Here's the effort so far of the design work.

Once I get the pieces cut out, I'll post back here if anyone's interested.
