3D model description

Update: added a front cover to increase strenght and to manage cables(M3X30mm bolt needed)

this mod is studied for the stock hotend and for the original motor, with the right length ptfe tube works also with flexible filaments.
NOTICE: this is a work in progress, using this and I'm really liking it, works well and I usually dont print faster than 60-70mm/s, with travel at 100mm/s , planning to upload other versions for different hotends but for it I'll need testers.

DESCRIPTION: after seeing many direct mod I've noticed that every mod just screws on the X carriage or reprints the whole X carriage, I dont like printed parts as structure and also I dont see real strenght in the few screw holes on the metal carriage, // THIS mod is studied to hook on the back metal caps between the wheels and the carriage, is the best possible mod and totally stable.

PRINTING:
suggested petg or abs, avoid PLA.

print all the parts, all these files are forks with little diferences from my older works and are studied for this , and only this mod.

motor mount: for best results print it as the file is arranged, just support from the build platform, yes it will be much support on the bottom but will print with best results the filament zone part

cooling files: there are 2 files:
one for a standard 5015 blower on the right
one (my favourite) a round mod for the nozzle it will make air in both sides with just a blower 5015 on the right, also the fan is hooked better and wont create vibrations.(printing: support only form the bed and change the density till u get a bit of support on the bridged part of the model)

choose what u like most

cooling fan for the hotend: doesnt need screws is just slide it on the heatsink , , is easier and more stable, print the one on this post, but follow the isntructions here:https://www.thingiverse.com/thing:2612897

MOUNTING:
for the lever:
1-m4x25mm -spring adjustments
1xm4nut -spring adjustments
1-m4x12mm -inside bearing holder

for the motor mount:
stock bolt on the right
M5x40mm bolt on the left

PTFETUBE:
should be about 72mm , not totally sure I've cutted mine bad

I apologize for my print photos, I've used hold printed parts :P

ALSO: a longer motor cable is needed
