Prusa i3 MK3S or something else?

[curious aardvark]

to make the cr10s better than a prusa you'll ned to add side support rails to your printbed and switch to a direct drive extruder :-)
They make the most difference.
All the fiddling people do with different hotends and extruders makes a lot less difference than you think.

My best printer has the most basic extruder and hot end you can pretty much get.
But the mechanics are right and that makes more difference.

Done and done. Plus the X-axis has been reinforced with 3/4" square steel bar to compensate for any added weight of the Micro Swiss DDE.

It's a fun project

So should I bother with linear rails on my Ender3? How would I mount the side support rails ?
