<div><p>Why replace the entire idler for about $6 USD when you can buy a pack of ten (10) new bearings for about $10 USD and replace the bearing in the idler for $1 USD each time.  This is setup for a Prusa i3 MK3/S&apos;s smooth idlers on the X and Y axis.  </p>
<p>I found these bearings to work well and do not cost much.  </p>

<p>See the pictures for the configuration for bearing extraction and insertion.  Both can be performed by threading a 3mm rod through and compressing, or using a pressfit vise, or a small hammer.  The key is printing the parts at 100% infill so they will not compress.  Bearing insertion must press against the outer rim of the bearing to avoid damage.  With bearing removal, it is not a concern since the bearing is old and will be discarded.</p></div>

623ZZ Bearing Pressfit tool for Prusa i3 MK3/S

Why replace the entire idler for about $6 USD when you can buy a pack of ten (10) new bearings for about $10 USD and replace the bearing in the idler for $1 USD each time.  This is setup for a Prusa i3 MK3/S's smooth idlers on the X and Y axis.  

I found these bearings to work well and do not cost much.  

XiKe 10 Pcs 623ZZ Double Metal Seal Bearings 3x10x4mm, Pre-Lubricated and Stable Performance and Cost Effective, Deep Groove Ball Bearings.

https://www.amazon.com/gp/product/B07JHT7D8R/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

See the pictures for the configuration for bearing extraction and insertion.  Both can be performed by threading a 3mm rod through and compressing, or using a pressfit vise, or a small hammer.  The key is printing the parts at 100% infill so they will not compress.  Bearing insertion must press against the outer rim of the bearing to avoid damage.  With bearing removal, it is not a concern since the bearing is old and will be discarded.

Nespresso rails & label holder

Refreshed design for the Nespresso original cup rail holder.


I changed the connection piece from the original design by the_mike because it was not printing nicely and did not fit together like it should.
So I simplyfied the connection piece, and added another "outtie" piece on the bottom part so I could add a label holder at the bottom, which is also included in this post.


For the label holder: no need to design your own format to fit into the holder. Simply cut off the lid from the cardboard box and slide into place. 

Print as many as you want, and use each rail for a seperate flavour. We will end up sticking it on a piece of black plexiglas, and mount that to a wall next to the coffee machine with double sided tape.

FD MK3S

Hi all,

Fist of all, big thanks to Pekcitron for his amazing work on Prusa Bear version. I was inspired by his work. Some of the parts I reused. All is possible to see in BOM pdf file.
This is FD MK3S, fully linear rail (PMI or Hiwin ) 3D printer with Prusa electronics. 
I rebuild my own Prusa MK3S to make my own FD MK3S. I´m really happy with results so I decided to share with you guys. 
In attach you find Bill of Material with QTY of each parts.Rebuild is not for beginner. From original Prusa will be used only electronic, step motors and extruder. Nothing more. 
I add also a STP file of whole printer. In files you can find also edrawings file. This is edrawings file from Solidworks. You can use it for your build. 

Support is only necessary for FD Z X Axis Slider LH.

Enjoy it

P.s. It is only for MK3S or MK3 Versions of Prusa. Didn't test the rest. 
Be careful, It cannot be rebuild on Bear Frame, there are changes in the length of profiles. Base is shorter.
