Z-axis bearing protection P1/P2 series

Z-AXIS PROTECTIVE CAP (P1S, P1P, P2S)

This is a two-part protector for the lead screw that moves the heated bed on the P1 series Z-axis. Its dome shape allows for maintaining a small reservoir of lubricant over the bearing

The idea came to me when I started seeing many filament fragments detaching from prints. Initially, I tried some designs, but none allowed for maintaining a certain amount of lubricant, in the way the printer originally came

I usually print in PETG, but I also upload the PLA option

The cap works perfectly for the P1 series and the P2 series. However, in the case of the P1 series, some users have reported the caveat mentioned in the IMPORTANT section, highlighted in red at the end of this publication. Regarding this caveat, I include a YouTube link and a GIF video version, which can be viewed directly from this page, where it can be seen that the print bed can complete its entire travel without issues

ATTENTION: Before printing, please note that if you voluntarily lower the print bed to the maximum of its Z-travel, it will lightly touch the cap. I believe this is not important, as prints of exactly 256 mm are not usually made, and in exchange for this small sacrifice of just a few millimeters, we will achieve, in addition to protection against filament debris, maintaining a small reservoir of lubricant on the threaded rod
However, if you consider losing a few millimeters in the Z-axis important, do not print these caps
