Bonjour Merci pour vos précisions

J'ai imprimé les 2 boutons ( Axe Z et Extrudeur ) les cotes sont OK

The difference between the Z lead screw designs are:
My initial design attached to the upper rail using screws and T nuts. I designed it this way as I had lights mounted to the upper rail that made it difficult to remove the upper rail to mount the lead screw support. This design allows the lead screw support to be mounted without any disassembly. It also allowed for some small adjustment for position/alignment.

I subsequently designed a new lighting system for my printer which is far superior to the previous version, and therefore removal of the upper rail was no longer a problem. I also found that I really did not need the adjustment that the first design provided, so I redesigned it for a press fit. This allows the lead screw mount to be inserted into the end of the upper rail and has a cleaner appearance, however it requires either removal of the upper rail or removal of the lead screw to install it, but it fits very nicely (I used the tight fit design).

The above two designs are not compatible with the mounting block for the filament guide, so I redesigned the press fit version so that it can work together with the filament guide. This design also requires either the upper rail or lead screw to be removed to install it to the printer, but it works very nicely together with the filament guide. I also used the tight fit version on my printer.

Bonjour Merci pour ce partage

Il faudrait préciser :

Qu'il faut imprimer sans support pour un bon fini de l'emplacement du doigt
Quelle différence entre les trois versions de guide axe Z

The difference between the 3 different Z axis supports are in the title of each link. One is push fit, one is push fit with filament guide and one is screw fit.
