My Yamaha SR 250 (1983 or 1984 I think) has an empty space where there used to be a tool kit. I've made a drawer compartment which fits into the space to hold the 50ml lead additive valve-saver fluid bottle I carry. The YAMAHA logo lid is an alternate to the plain one, just in case you feel like celebrating Yamaha as a brand on your new compartment. Made with AutoCAD3D. Updated 11 June 2013: the compartment was too tight a fit so I reduced it to 95% of its original size.The compartment: print 0.27mm layer height, 2 shells, 100% fill, no raft, no support. The lid: print print 0.27mm layer height, 2 shells, 15% fill, no raft, no support. Acetone glue open end of compartment to the flat side of the lid.
