Has your plastruder ever self-destructed? Has the filament guide middle cracked? Behold the Replacement Parts! These are parts that often break in the plastruder. Right now I only have filament guide middle but more are to come. Or you can ask for any lasercut part in the plastruder and I can whip you up a replacement part design.If you would like the source, just ask and I will upload. I use Sketchup.NOTE: This is still untested. Please let me know if this works or if I have to scale it differently. Darn Sketchup imports DXFs at a ridiculous scale and I have to experiment to get it the right size.UPDATE If you have downloaded the Filament Guide Middle or Insulator Retainer before 12/6/2010, then you will need to redownload. New versions uploaded that are much more dimensionally correct.Temporarily fix your plastruder (if possible) and print (or ask a friend to print one). Then simply drop in your replacement. Please provide feedback if it doesn't work like the lasercut version.
