JustinO Posted June 18 Share Posted June 18 HI all, a tale of woe (well, minor inconvenience)... I recently lost my port cap for an m67 port when surfacing from a dive. I replaced it at the end of the dive, waited for everyone else to board in the swell, and then handed up my rig. Not long after, I noticed no cap... it wasn't on the boat, so it's lost. Lesson learned on securing such vulnerable bits of kit. But my question is, does anyone have any ideas for a suitable replacement at better prices than a genuine replacement (£22)? THe part is here: macro port cap There's a huge selection of m67 caps out there, but any advice to help me get a "first time right" replacement that grips the port well gratefully received... I am sure i am not the first, nor the last to suffer this. I've drawn a blank on old threads on WetPixel. Cheers in advance Justin 2 Link to comment Share on other sites More sharing options...
Davide DB Posted June 18 Share Posted June 18 Hi Justin, I can confirm that this cheap generic M67 cap bought on Amazon last year for a Yashica vintage lens, fits perfectly on my M67 Nauticam CMC-2... https://www.amazon.it/Ares-coperchio-obiettivo-copriobiettivo-Fujifilm/dp/B078178P8W/ref=sr_1_3_sspa The only "flaw" for our use case is that it does not have a hook for a lanyard but I am sure you can find it on Amazon. 1 1 Link to comment Share on other sites More sharing options...

Chris Ross Posted June 19 Share Posted June 19 Walk into any camera store and buy the off brand caps - they however are very easily dislodged as is the genuine article, I think tight fitting neoprene cylinder like a stubby cooler and attaching a lanyard to it might in fact be a better option. 1 1 Link to comment Share on other sites More sharing options...
Tobyone Posted June 20 Share Posted June 20 (edited) Have someone 3D print out of TPU. Have a few made. Easily done. The attached STL file has my name on the cap, but it can be removed(covered up). It fits the 67mm Nauticam port 45. V3v Port 45 .stl Edited June 20 by Tobyone nauticam got spell checked to nautical. 2 Link to comment Share on other sites More sharing options...

Tobyone Posted June 20 Share Posted June 20 Yes. The flexible material allows it to hug the rim. You could play with ID to adjust the tightness. 1 Link to comment Share on other sites More sharing options...

Tobyone Posted June 21 Share Posted June 21 Sliced in Cura for cruelty c10 v2. Print logo up with tree supports 10%. Sizing works good for port 45. Might need to be tweaked for different printers. 1 Link to comment Share on other sites More sharing options...
JustinO Posted June 25 Author Share Posted June 25 (edited) This is what I went with in the end: Ulbter 67mm lens cap cover It comes in a twin pack, with two elasticated lanyards that slip nicely over the port to help guard against loss. Fit is very snug. You can also buy the elastic lanyards separately in case needed. Now I have one spare to put on my CMC, and all for about one third the price of an original... Davide, there's a beer with your name it on it if we ever bump into each other. Cheers. Edited June 25 by JustinO typo 1 Link to comment Share on other sites More sharing options...
