A 3d printed expression bar

"The Apollo" - An electric expression bar

N=1 design. A build for a friend and a challenge to myself to go from ideation to completion in 4 weeks.

First step, introduce the project to the user and discuss what I thought were the desired solutions. Second step, throw out my original ideas. The new goal was to make a guitar mounted expression bar, allowing the user to control pedal effects via a hand control, solving a combinations of problems.

The first prototype was functional but bulky.

The second prototype was much smaller but still needed some work done with the clamping system, at this stage the set width was designed for a specific guitar width. An on on switch was added to allow for a reverse of the control

Next, lots and lots of tuning the form.

Testing printed parts for tapping and metal hardware.

The end product included aluminum reinforced resin parts, a pivoting jaw to allow for convex guitars surfaces, adjustable clamp width, adjustable bar length and much more.

See below the initial testing by the user.
