These attachment pegs are derived from the Magnet Locators (http://shpws.me/KwPL), having been requested by some players on the Aerodrome forum.
Printed in WSF plastic, these pegs are designed to be glued underneath the fuselage of a plane (e.g. a Shapeways 3D-printed one) to provide an attachment peg of the correct dimensions and angle to firmly seat in the top of a flight peg. Available for fighter and bomber size pegs.
The 'shoulder' of the peg protrudes approximately 1mm beyond the top of the peg when snugly seated. The diameter of the 'shoulder' is approximately 4.2mm diameter.
Supplied on a sprue of fifteen. Also available as a sprue of five (http://shpws.me/Kx1A).
