New rigid header for FT5

thingiverse

20170228 : Attention -- Possible issue when in a hot environment I encountered a tolerance problem while printing with ABS. The top part of the printer was at around 50°C and thermal expansion caused step skipping due to grinding between the stepper motor and the 2020-profile. I've added some extra room (2mm) between the stepper and the 2020-profile with new front and back plates. Unless you only print PLA, I strongly advise using files FrontV2.STL and BackV2.STL !! I tested and it works nicely now. See last picture for the added room between profile and stepper. I also designed a new TOPV2.STL for the cablechain mount. This one has, like the bottom piece, complete support for the bolts. A redesigned header for the FT5. Push once to the tip of your hotend to the back/front to see what I mean with rigidity. Extra support for the bolts, extra ribs on front- and backside, higher bottom- and top part give extra rigidity to the header. Absolutely no play in Y-direction anymore. The top part has integrated nylocks. Nylocks fit quite tight (you don't want to loose them when everything is mounted) : use a bolt to pull them completely into their seat. (see pictures) The bottom part has an integrated support for mounting a partcooler. If you have a Titan/Volcano, you could use the design from the pictures. Bolts to fix top part on slider are M3/12mm Mounting is quite straightforward.
