Recommend adding thread locker to M3 SHCS attaching linear rail to center section.

After about 50 hours of printing I noticed the entire print head was coming loose. After disassembly I found the three M3 SHCS attaching the linear rail to the center mounting structure were all coming loose. I've gone back and added blue Locktite to each of these screws to fix the problem. I would recommend adding this to the assembly manual in future revisions.

Sorry for the very late response. R8 redesigned this part to improve this. I don't recommend threadlocker in plastic parts, many threadlockers are not compatible with ABS and will degrade the part.
