Double extruder mod Printrbot Simple Metal
Description
This Is An Experiment To Mount Two Extruders As Close As Possible To Each Other On The Printrbot Simple Metal With No Modification Of The Printer Itself. Print With As Much Infill As Possible For Rigidity. Not Strong Enough For Real Intensive Or Prolonged Use, But Perfect For Proof Of Concept And Experimenting. Bottom Must Be As Flat And Straight As Possible. I Recommend Using A Heated Bed If Possible, Or If Rafts Are Used, Sand The Bottom Surface Well Since It Will Determine The Parallelism Of Both Extruders And Their Alignment With The Y Axis. You Might Have To Shorten The Shaft Of On Of The Two Motors For Them To Fit. The Original Printrbot Fan Shroud, Or Any Fan Shroud Made To Fit Standard Extruders Wont Fit Because Of The Hot Ends Being 5Mm Higher. Good Luck :-)
