OP-1 LEGO Shaft
thingiverse
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 ensure a reliable fit, closely emulating Teenage Engineering's original part. The axle can either be glued into the shaft or friction fitted securely. V2: Increased clearance for a smooth connection to the knob.
