This camera adapter for the Craftbot+ uses the raspberry pi camera with a fish eye lens that can be found on ebay. It uses the existing M3 on the right hand side window to attach, so no modifications to the printer frame are necessary. The camera points down by 15° and 50° inwards to give a good overview of the interior or the printer for. Using a fish eye lens (130°) allows for a full view of almost the entire build volume.

BOM: 1x M315mm (the stock screw is to short, so it needs to be replaced by a longer one) 4x M215mm 1x 1080P Camera Module Board 5MP 130° Fish Eye
