Well, im building a rack tomorrow (adult 41 qt rack), and i have to melt ventilation holes on the sides of the tubs... And man does that take long!... BUT! I thought of an amazing idea that would be very useful (among the reptile community that is..), and that idea is to make a soldering iron basically, but instead of just having that one tip, there would be a bar type of thing with many tips on it (about 10), that all heated up and this allowed you to melt several ventilation holes at once instead of one at a time... Let me know what you think... Maybe its already invented? Im not sure...
