Launch pad for model rocket

Launch pad for model rockets. ====================== Designed specifically for my modular rocket project [www.thingiverse.com/thing:3583502](https://www.thingiverse.com/thing:3583502) but can also be used with other Estes or sugar-powered rockets that require a guide rod for stability. It's best to print the launch pad with the 10 inch (250mm) leg for better stability on rough ground, however the 6 3/4 inch (175mm) leg is provided in case the longer legs won't fit diagonally on your printer bed. * Print 1 x launch pad, 3 x leg and 3 x screw. * The launch pad and screws should be printed with a 0.2mm layer height or less to ensure that the screw threads are well defined. * Print the 3 screws together as one job without any other components to ensure good adhesion of the layers. * The legs may be printed in draft mode with a layer height of 0.25mm or higher. The optional blast deflector plate can be printed in a higher melting point plastic such as ABS so that it will last longer, however I have tested it printed in PLA and there doesn't seem to be any melting. Alternatively use a metal lid from a tin, punch a hole in the center so that you can fix it onto the launch pad with a small screw. Assemble the launch pad and fit a wire rod at least 2 feet (600mm) long. There are four holes provided which will accept a 2mm, 2.5mm, 3mm or 3.5mm diameter rod (a wire coat-hanger straightened out is suitable).
