Canon EF Macro Extension Tube 48mm

thingiverse

I remixed SkyRzn's extension tube set as i found the walls of the tube to be very thin and compression on the sides could result in some bending of the walls. This could result in a broken extension tube overtime and/or a dropped/broken lens. I added a few mm to the wall thickness to fix this issue. I also remixed it to 48mm. I did this because I only have white or red filament and I found that light colours of filament let light through the side of the macro tube, this light lands on your camera sensor and makes the image look much worse, my solution for this is wrapping the tube in packing tape to stop the light transmission into the tube. Standard packing tape is 48mm wide, hence the 48mm tube.On my 90mm 1:1 macro lens this tube enables me to get 1.53:1 sized images on the sensor, with two of these stacked on top of each other then I can get 2.06:1 sized images on the sensor.
