I've had some interest in acrylic cases lately, I made one for myself and a few people have asked me if I can make them for them. I'm using 1/8 inch cast acrylic, cut on the laser and IPS weld on 3 to bond them. The problem I'm having is they seem to come apart at the seems on the open side of the case. Is there any way I can make the bonds stronger? I'm trying to make them as bubble free as possible, but that's pretty tough. I've even made squared locking corners, but that doesn't seem to help either. They are ok if you handle them lightly, but some pressure will break the seam open. Any advice? It seems like I'm sitting on a pile of business here, but it does me no good if the product is lacking lol.
