Launch pad for model rocket

Launch pad for model rockets.

Designed for my modular rocket project www.thingiverse.com/thing:3583502 but will work with other Estes or sugar powered rockets which require a guide rod for stability.

It is best printed 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 will not fit diagonally on your printer bed.

• Print 1 x launch pad, 3 x leg and 3 x screw.
• The launch pad and the screws should be printed with a 0.2mm layer height or less in order 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 layer height of 0.25mm or higher. The optional blast deflector plate may 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 does not 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 4 holes provided which will accept a 2mm, 2.5mm, 3mm or 3.5mm diameter rod (a wire coat-hanger straightened out is suitable).
