All printable Z-axis and bed holder

Full printable, complete Z-axis solution for all lift platform 3D printer.

The Z axis based on current tests, it is a very rigid mechanical structure.
When fitting for something far greater than 0.2mm were posted were in the carriage as the axes of the bearings. This track ends caused mild constipation. Grinding and clamping bolt tension by changing, I corrected the error. Now moving nicely.
If I have time, I'll try another solution.
Everything else was problem-free to put together.
