  • BLN-1 Battery Cases

    Having looked for some simple covers for my EM-1 batteries and not finding any, I opted for small Ziplok bags. I put one in each, especially when "flying" because of the rules on carrying extra batteries safely. I then put them all in a small cloth glasses bag and get one out when I need a charged one, putting the dead ones back into the camera bag (in its Ziplok) not into the glasses bag!

    NOT ANY MORE!!

    I have "invented" the BLN-1 battery case. It is "additively manufactured" from PET and comes in a 1, 2 ,3 or 4 battery configuration! It has taken a while to get it right but I'm happy with the result.











    I'm quite surprised how strong they are too. A single holder weighs just 6 grams.




    Nothing round the back....



    Olympic Gold!




    I also made a marking gauge to put simple red and green marks on the battery. I then post it back in the appropriate way.






    Just poke your finger in the bottom and push the battery up then pinch it out from the cut out on the top.

    What a neat idea. I have 4 of these batteries and an eternal problem keeping charged and dead ones sorted out. I may just have to be your first customer

            Ron,
            they are for sale, but where it is a profitable enterprise remains to be seen!

              First 3 orders posted out, looking forward to some "user"comments!

              If anyone has an idea they need "prototyping up" then I could be your man.

              I may turn my attention to some macro flash diffusers next!

                I guess you've got yourself a 3D printer! I've toyed with the idea on and off for a while.

                  I ordered a small selection from Andrew and they arrived safely today. Just tried some batteries in them and they look really good - nice snug fit but reasonably easy to slide the battery in and out. The marking gauge is small and just asking to get lost, though!

                  Many thanks to Andrew, what a great idea, and well implemented.

                        Re: BLN-1 Battery Cases

                        My "4-up" arrived today, after a hiatus for re-delivery when I was out on Monday.

                        It's great! Batteries fit neatly, the whole thing will sit nicely in a pocket of the camera bag, and the green/red marking idea is perfect for indicating the live from the dead.

                        Now I just need to remember where I actually left that 4th battery, and I'm in business!

                        Thanks Andrew!

                          Hi Beagletorque! Do you still make battery dust/end caps? I'm after some for Olympus BLS-5 batteries. I've looked everywhere for them :-(
                          What do Guinea pigs test things on?

                            Hi Sue,
                            I do have some remaining "stock" of holders for the BLS-5.
                            I have single, long double and long 4 in silver as per the photo below.
                            It is shown with a genuine BLS-5 which fits fine.
                            Zuiko (John) was kind enough to test the holder with replacement types and he found that the fit was also acceptable.
                            Regards,
                            Andrew

                              Hi Beagletorque

                              Oh the end caps look fabulous! I'd love to buy 2 singles & 2 doubles if possible. Can I pay by PayPal?

                              Thanks in advance
