Our custom made Maser Cannon fits perfectly in the area just next to the Maser Cannon on the playfield.  Includes double sided tape for easy installation and alligator clips to attach to the GI lighting for power.  It will even flash when the GI lights do!
 
We also have UFO acorn nuts (and many other styles) that mimic the UFO graphics in this game (see other listing). They replace the 6-32 sized nuts
 

Remember, these are all 3D printed and there may be some slight imperfections.
