Description

This is a design for a /really/ inexpensive linear axis mechanism for an open source selective laser sintering 3D printer that I've been designing (but it should be generally useable for anything that requires a one or two axis system). This is a follow up to the selective laser sintering alpha one dual Z tables that I recently posted ( thingiverse.com/thing:3390 ).

The innovations in this system are its extremely minimal vitamin count -- only a handful of bolts, washers, and nuts are required. It also uses several long pieces of kapton tape as a linear slide bushing, to dramatically reduce friction and drag (though regular old scotch tape may work just as well ;) ).
