M42 Macro Extension Tube - 10mm/20mm/36mm

3D model description

A quick remix of Murin's M42 macro extension tube. I chamfered the inner ring to make this print without supports, and adapted the size to standard extension tube ratios. It comes in a 10mm, 20mm, and 36mm size.

I would recommend first printing the 10mm to check the tolerances of your printer. If its not an exact fit as is, you can increase or decrease the x and y sizes in your slicer, while leaving the z the same. This allows you to easily make minor adjustments to the diameter.

As mentioned in the original, print this at 0.1mm or else the threads will be too thick to function properly.

I love to create models and 3D print my own designs. There's something about taking something virtual, and making it a real physical thing - its almost magical.

As much as I enjoy creating things, I also love to see other people enjoying my designs. If you print something, please share it with me. It motivates me to create more!

I also do requests. Sometimes I just run out of ideas, or I want some new challenges. If you have something you would like to see, or maybe you just want some help with something you are designing, give me a shout!

(I also wont refuse tips, I have bills to pay after all.)
