Mk3/S Bear Y linear rail upgrade

CAUTION : THIS THING HAVEN'T BEEN TESTED YET AND SHOULD REQUIRE SOME FIRMWARE ADJUSTMENT (take a look at the link below to have the best chances of succeed)

If you try it, please comment your thoughts.

Hi, I planed to upgrade my MK3S Bear with linear rail, just like the watterott upgrade for the regular mk3/s but for bear. This is design to keep the z height exactly the same. I create this from the rod holder by pekcitron and the watterott model for "template".

Should be printed as it is with support. (integrated supports since V2)

Follow the instruction given in the link below to mount it.

https://learn.watterott.com/3d-printer/mk3-y-upgrade/assembly/

Hardware needed:

V slot mounting : Same as rod holder by pekcitron

Rail and carriage mounting : 10x M3x10mm

Rails : 1x 330mm + 2 MGN12C carriage

1x 330mm + 1 MGN12C carriage

If you want to buy hiwin rail directly, consider buying it here to support watterott: https://shop.watterott.com/Y-axis-upgrade-kit-for-Prusa-MK3

I hope you'll enjoy it and if you like it, don't hesitate to throw a tip to support me :D

EDIT 27/06/2020 :

I added a build helper, it need to be 80.75mm to set the rails at the exact position as the "original" rods and also, bring in a V2 of the support with integrated support to have a better precision.

EDIT 15/07/2020 :

I changed the design a bit to help keeping printing area, i delete by the same time, the two previous versions.
