I spent 1 hour drafting this 1911 grip with a ribbed texture on CAD program so it is free. It is derived from Thingiverse thing number 610087 by "Printedfiream".However, I spent 48 hours designing an original draft of another pair of 1911 grips that has a very nice checkered texture. It is available on http://www.3dprintfilemarket.com/150516092445grips1911.html Print this without support nor raft.
