OP-1 LEGO Shaft

This is a customised easy print version of the Teenage Engineering OP-1 Brick Shaft.

The only non 3D printed part required is the Lego Technic Axle 2

The Lego axle is the easiest way to have a reliable fit, emulating Teenage Engineering's original part closely.

The axle can either be glued into the shaft, or friction fitted.

V2: More clearance for the connection to the knob.
