Rival Flame Thrower Barrel Attachment

Made my N-Strike barrel attachments work with rival. I added modifers to the models in the 3mf file to print 100% on the lugs. Three models, one and three have different sized holes. NOTE: to fit the Mirage XXIV-800, lower the model (Z Axis) 1.2mm (From 38.33 to 37.30).
