Racktime 70mm to 120mm adapter

thingiverse

I purchased a Racktime Boxit Cage for transporting my equipment to and from work. Unfortunately, it didn't fit on my existing Racktime rack. My bike has a narrow rack with 70mm inner spacing. To solve this problem, I created an adapter that converts 120mm accessories to fit the narrower version of my rack. Essentially, I made a wide-to-narrow Racktime solution. Please note that using quick releases won't work in the same way as before. In that case, you'll need to modify the size of the holes.
