Is there any exploded diagram of the tool head with all the printed parts named? In particular, what is the name of this print part? The extruder body? ![](http://3dprintingforbeginners.com/wp-content/uploads/2016/05/LulzBot-Mini-Review_433_2.png) Mine has developed similar cracks and I would like to print a new one before the printer is out of commission. For those who have printed this part, can it be printed without supports? What infill did you use? Thx. ---

Poke around here for a bit: [https://ohai.lulzbot.com/](https://ohai.lulzbot.com/) Also, your mini should have come with a usb drive that would have all the files for the printed parts that are on the machine. ---

If you’re going to print it, production printed parts are 85% infill. ---

Using ABS and this gcode file of the current release of the part - printable on your Mini: [http://devel.lulzbot.com/mini/foxglove/production\_parts/printed\_parts/extruder\_body\_3mmhex\_Mini/MINI/extruder\_body\_hex\_v1.4.1-15c-50m.250.110.gcode](http://devel.lulzbot.com/mini/foxglove/production_parts/printed_parts/extruder_body_3mmhex_Mini/MINI/extruder_body_hex_v1.4.1-15c-50m.250.110.gcode) ---

I printed a spare in Alloy 910, probably just in the nick of time as I see cracks on both sides of the body where the nuts slide in(probably the weakest part since there is not much material there due to the cavity.) Anyway, I 'll see how long it holds up and then swap it out when the printing is affected. I also printed the beefy idler and idler latch from the devel branch.
