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.

Platform holder due to the large size, to be printed and put together five pieces.
Central bracket length 180mm. While large pieces, but it fits easily into a standard 200 * 200mm printers.
Printed pieces should just slide into each other. Then, fixed screws. Because of the same self-positioning, assembling when you may need a bit of insistence.
Put your all the nuts into place formed. The PLA is too weak for metric threads.

Attention!
The PLA will melt very easily. Already at 40 ° C decreases the strength.
do thick insulation under heated bed.
Leave a small air gap between the support and bed.
Do not use fully enclosed and heated workspace.
As well. Do not swallow the small parts. And do not dry the cat in the microwave oven. ;-)
