Filter Case, 67mm

thingiverse

A case for 67mm photographic filters. It uses 8mm X 3mm (diameter x thickness) neodymium magnets for closure. This is a remix of my 95mm case. I found I had filters of various thicknesses. I modified the design of the case bottom to accommodate the different thicknesses, so the magnets will strongly hold the case closed. There are bottom STLs for 7mm, 8mm, 9mm, and 10mm thick filters. You can use the thicker versions for all of your filters, or customize and maybe get an extra filter into your camera bag. I designed it to add the magnets after printing, using epoxy to glue them in place. ==================== Magnets - 8mm X 3mm Take care to ensure that the magnets in the corners are all oriented the same way. Failure to do this will result in problems, such as the lid only working when turned a particular way. I prefer using a 2-part epoxy for this, as it will adhere to the magnets and the print and produce the strongest bond. Glue the 4 magnets into the recesses in the lid first. When they are done and the glue has set up, put the lid on your work surface WITH THE TOP (OUTSIDE) UP. Then place the bottom half of the case ON TOP of the lid, so the bottom of the bottom is in contact with the top of the top. Put a drop of epoxy into each of the recesses in the case bottom, then drop a magnet in -- the magnets in the lid, underneath the part, will force these magnets to flip into the correct orientation. If you make cases for multiple filters, make sure to orient the magnets the same way in all of the cases, then the cases will stick together -- not too tightly -- keeping things in your camera bag neat and organized.
