Well I cut out a nice piece of Extra Firm foam I have to fit my pelican case so I don't have spaces "ghetto rigged" to hold lasers and optics since the collection held in this case has changed drastically. I can get this foam real cheap (About $5 for a block that has more then enough for two cases) so I'm not too worried about having something I will need to change. Right now I have three Pen lasers and one DIY Red Mini Dorcy and I'm not sure how I should set up my case. Due to the density of the foam and how I can easily change it I was even thinking to set up two layers and have the lasers on top and optics, batteries, and other accessories on the bottom. You can see in the picture how my pluck foam was cut before and am open to any suggestions on how to set this up.
