Z stabilisateur / molette de réglage et guide filament U30

thingiverse

I have provided this stabilizer support for the Z axis for several reasons: to stabilize the axis without constraining it for better guiding accuracy and to align the rod as much as possible parallel to the mounting alignment, avoiding accidental clings to the T8 rod and allowing easy raising and lowering of the Z axis for adjustment and maintenance operations. No piece of the Z axis comes into contact with the support, even in abutment. I have tried to show this on one of the photos. To install the support, it will be sufficient to tap the left end of the 20*20 profile in M5 using a self-drilling screw of 5. To fix the support on the left side, use a countersunk head screw M5x13. On the back side, use a standard M5 nut that is lightly filed on two edges of the same face or an M5 hammer nut and a countersunk head screw M4x12. The 608 bearing is retracted and maintained by pressure (set at 0.2 tenth at design). I installed it without forcing too much with my hand, then with a joint serves a mesh will suffice by patting. The calf is not tight fit; you can print at 99%. If the calf is a little loose or does not hold well, use a little brake spun or a drop of paint type glycero to maintain the calf and be able to disassemble it when needed. No support is required nor brim. https://youtu.be/Ss3Murb9DzM BOM: 2 x countersunk head screws M5x13 easily found in a DIY shop in the hardware department. 1 M5 nut slightly filed on two edges of the same face. 1 bearing 608, r, rs or 2rs in 22x7x8 internal diameter.
