Linear Rail Bath - Any Length

I had some long 560mm linear rails for the x & y axis update to my Neptune 4 max.  None of the existing baths I found on Printables had the length for the MGN9C's.  So I made this.

It has 3 basic pieces:

1. Male end
2. Center
3. Female end

Print them out and glue them together.  

I use 30 minute epoxy glue and there were no leaks when I used the bath after an hour of curing at 28C.  I used a straight piece of wood to keep my rails level and some cut out from plastic bags to stop the epoxy from sticking to the wood as well.  I found if I waited for 30-60 minutes when the epoxy had begun to harden enough to no longer be sticky I could peel off the plastic underlay without it tearing.

Start by measuring your rail and then choose determine sizes of the three sections, Male, Center & Female from the existing 3mf center sizes that you need to fit it.  I have included 200mm male and female ends as well as 50mm,100mm,150mm & 200mm center sections to vary the size.

If that doesn't work go into the FreeCad cad file and tweak via the spreadsheet.  Fully parametric can be easily widened for MGN12C rails, see the comments in the spreadsheet.

There male section also comes with a roof or tunnel option that you can use to stand the bath up on an angle and completely fill that end with solvent.  Placing the carriage in there allows it to be completely immersed for soaking. This lets you use less solvent to completely immerse the carriages that need the majority of the cleaning.  

I did this and left my carriages to soak for 15 minutes for each rail as well as 5 minutes flat. 

I also created some joining blocks that can sit inside the rails to make the glue up easier.  

I also made some rail sleepers that can sit in the bed to raise the rail just enough to lift the carriage off the bottom allowing it to slide along in the bath.

There is also a version of the sleeper for outside the bath for when you start lubricating them.

I found this https://www.printables.com/model/681840-linear-rail-lubrication-applicator-for-lucas-white on a tube of Superlube to lube the rails from the back.

I printed in old PLA with 0.4mm nozzle and 15% infill on Bambu X1C.
