universal macro bellows, lens and body mounts can be easily swapped out. belt drive for fine tuning magnification .
currently supports ef and ef-s body's and fd lenses. mounts can be easily swapped out, if you want to use a different lens or body you'll have to make your own (just find a lens/body cap model and combine it with a mesh from this model). step files included.

how to make bellows.
the total length of your unfolded bellows should be roughly 1.6x the length of the 8mm rods. i used 250mm rods so the total length of my bellows ended up being close to 400mm.
follow this tutorial on how to make bellows:
and use these dimensions:
print settings:
0.2 layer height
0.4 line width
4 walls
5 top/bottom layers.
support: yes, some parts need some minimal support material, use your own best judgement :)
you'll probably need to change the part orientation in your slicer.
material: pla should be fine for most parts, lens/body mounts can be a bit fragile so use something with good layer adhesion, i printed mine in abs but petg would probably work better.
