I built my own lomo case out of an old luggage and leftover foam pieces. It is free, cheap and I had it customised to myself and my cameras, and did I already mentioned it's free?
First find a sturdy, lightweight case..(second hand store, mom’s closet?) I used 70’s hard case luggage. Something you won’t hate carrying around.
Second find Hard yet pliable foam. Try your local hardware store, the bigger, the better. Larger stores go through more foam and custom cut it for customers needs, and are likely to have “extra pieces” for free. While your there, pick up some contact cement or spray glue. Think of your Dad’s got some in the shed.
Alright construction time. Measure the case, measure and cut the foam to fit the case. (2 layers of foam to fill the entire bottom cavity) Glue the bottom layer in whole. Don’t glue the top layer yet, lay out your cameras and accessories the way you want them and trace it with a pen. Next, it’s cutting time. Cut out all your holes carefully using a box cutter.
Now we can carry our precious Lomo cameras with confidence no matter what the location or conditions you’ll be.
