I built a trap to catck a bad crab I have, needless to say I didnt catch it but it did work nicely for a fish trap. I used 1/8" acrylic and glued it with weld-on leaving the top unglued the rubberbands hold the top on for easy removal. you bait it with whatever you want leave it overnight and hope for the best. I still havent caught the crab but it worked fer the pygmy angle!
