Useful upgrades

Hi,
I'll receive my MMU for the MK3 soon and in consequence will have to do some disassembly and maintenance on my printer. Since I am at it, I am wondering what printed parts upgrades would be useful to do. I'll get the new extruder fan parts anyway and the flexible sleeve, but there was also a suggestion for dented belt rollers for x and y axis and I can't find the size reference for those anymore.
Any other suggestions?

Thanks
Berthold

Is it worthwhile to get IGUS linear bearings for the bed?

Re: Useful upgrades

I took mine off and replaced with lm8uu on wednesday and I won't use them on my prusa's again

started jamming after a short period of use

Joan adjustable X axis belt ends and adjustable y belt end might be good

Are you referring to this?

That seems like a lot of trouble and modification...

Installing the R3 extruder - mainly for the textile sleeve - and giving your machine a thorough mechanical review to correct assembly errors is your best possible "upgrade".

Print yourself the new Einsy enclosure with the cable clamps!

Is not SCAD, Prusa "improvements" that don't include source code are evolutionary dead-ends for certain.

Also the current X-Motor end design has integrated post-assembly belt tensioning.

Hi again,
Just another quick question before jumping on exchanging the standard idlers for toothed ones.

What is the primary benefit for doing this modification and why doesn't Prusa supply those idlers in the first place? Is there any advantage to using idlers without teeth?

Thanks
Berthold
