Canon EF to RF Drop-In Filter Case

Customized prints are also available at my Etsy store. https://etsy.me/3y5OTfL

This is a case for Official Canon Drop-in Filter Mount Adapter EF-EOS R. If your like me and think the case that they send these filters in is ridiculously big then this is for you. This case allows for each filter to fit tight and lock in place. The audible locking "Click" assures your filter is safely locked in.

WARNING::
The case has been fitted for the Canon brand filters. Off brands seem to be hit or miss because of their varying dimensions. The ones that don't work usually also require their own ef to rf adapter to be use also. If you are using filters that fit the official canon adapter you should be fine. Please purchase with that in mind.

This file pack includes 1,2,3,4 slot cases in .3mf format.

Requires no supports but requires a well calibrated printer. Usually culprit is e-steps being off will make the slots too tight for the filters.

Please feel free to share images of your prints on this page, I would love to see them

Thank you

It does not require supports, I suggest you use a perimeter of three or more lines. One side has a thin wall and requires it to be solid or can possible snap if enough pressure is put on it while in backpack. Print speed of 50mm/s infill at least 20-30% for strength. Tolerances are tight to the filters so any blob, zit, or other anomaly will hinder filter sliding in.

Recommend PLA or PLA+. PETG and other may warp a bit making filter slot too tight.

It is an easy model to print, but if you have issues with filter fitting to tight please check your e-step calibration for your extruder.
