3D printed steerable borescope

I recently had a need to look under the floorboards to check on some pipework and the only easy access was a knothole less than 20mm diameter. A cheap borescope (£7.00 on eBay) gave a good picture but was difficult to manouvre to see what I was looking for. An unwound wire coat-hanger and electrical tape prove no solution so I quickly printed up a borescope steering mechanism based on what little information I could find on medical endoscopes.
