62mm to 77mm step up ring for ND/CPL filter

thingiverse

This is a step up ring adapter from a 62mm lens to use a 77mm ND filter/CPL filter. I use the 3D model of the 77mm lens holder from geek7 and the 62mm thread section from another creator but I cannot remember where i sourced that from. So credit should be given to that 2nd creator in any case. The 77mm lens holder has no thread to it, but i find that it fits perfectly for my 77mm filters, which just snap into place and won't fall out. I split the 2 sections so that i do not have to use any supports - and i then glued the 2 pieces together. I just use 0.12 layer height - but maybe this should be 0.10 to be smoother.
