Wanhao Duplicator 4S Tool Rack

I was fed up with stashing my hex keys, spanner and scraper in the body of my printer so with 2 nuts n bolts being nicely placed at the top of the window i made this

holes for hex keys
Box for spare screws bits n pieces
Slot for a scraper
Front holder for a 6mm spanner

Photo shows earlier version where i hung the spanner from a hooked version as an after thought
