P3Steel T5/T8 X-Axis parts (based on toolson's MK2 edition)

thingiverse

I designed these parts back in 2017 based on Toolson's P3steel toolson edition MK2 files that can be found here: http://scheuten.me/wp-content/uploads/2017/05/P3sTE_MK2_r02.zip. The original STLs were imported into Fusion 360, converted from mesh to BRep and then pretty much redone from scratch anyway while preserving dimensional accuracy. You'll still need Toolson's P3sTE_MK2_X-idler_v1_2_r.stl found in the source above to complete this setup, so technically this is a remix that I can't point to within Thingiverse because it's based on an external yet free for private use source. I strongly recommend checking out Toolson's blog at http://scheuten.me/ for lots of useful information. My reasoning for redesigning these parts was that Toolson refused to provide parts designed for trapezoidal lead screws due to their cost back then. As we all know, prices drop pretty quickly sometimes and I really wanted to use T5*2 lead screws in my own build so I had to go my own way. While some might argue that T5 lead screws are "fIimsy", I like the T5 lead screws because they have some flexibility (i.e. they bend more easily) than T8 lead screws and that compensates for many inaccuracies in your P3Steel build. I also strongly advise against constraining lead screws at the top of the Z-axis by aligning them with bearings or the like as it introduces more problems than it solves, IMHO. That way, the stability of the Z-axis is based on the Z-axis smooth rods while the lead screws' job is to take care of the movement without adding unnecessary over constraints on the whole movement of the Z-axis that might lead to ugly inaccuracies in your prints. I've been using the x-axis parts for about two years now with some cheap Chinese T5*2 lead screws and couldn't be happier. Try them for yourselves, YMMV.
