If you have an object with that texture on it, you could make a very thin slice of it, line it up on your part, and either do a combine or subtract on it to add the texture where you want it.

No, there isn't that ability (yet), but you can turn the object into Support material to turn it transparent. That will allow you to see through the object for alignment purposes.

You can do that like this

You can do that with the alignment tool.

@bionicback321 You can make a hex (or any other polygon with n-sides) with the Circle primitive. Just change the number of sides to what you'd like

@tinken no disagreement overall, just making sure that issues are addressed in the most logical order. I'm hesitant to recommend things that aren't regularly necessary because I've seen some absurd things over the years - including people loading up with lithium or moly grease to the point where it gums up the lead screws/nuts and requires full replacement of the nuts and printed parts. A dry lube or a penetrating film type lube like you've described TinkSeal being would be much better options than a grease or oil.

@tinken correct, Delrin/POM is not impregnated with lubricant, but it really shouldn't require lubrication in this application. And, using the incorrect lubricant can cause issues. Our Pulse print farm that runs 24 hours/day, 5+ days/week for the better part of 4 years hasn't required Z-nut lubrication.
I'm not familiar with TinkSeal, so I can't recommend it, but it would be very rare for an issue to be related to Z-nuts not being lubricated.

You should not need to lubricate your Z axis screws/nuts. The nuts are made of Delrin and really shouldn't require any additional lubrication. If you are having issues with your Z axis movement, you can remove the Z motors and clean the lead screws with alcohol. Then you can use light machine oil or mineral oil to give it some protection. Wipe off any excess oil before reinstalling.

@rbradford1111 I removed one sentence from your comment. You're free to criticize and complain on the forum, but you don't need to use offensive language to do so.

Sorry you're upset with the printer. I'm happy to help with any specific issue.

As for the fan "issue", the Azteeg board and the BSD drivers are rated for well above what they are running at. Active cooling is simply not necessary - even in a passively heated enclosure. The Prusa, which you are fond of, doesn't have a case fan and the Einsy Rambo 2130 drivers run significantly hotter than the Azteeg with 2660 drivers. Further, there are giant heat sinks on the 2660 drivers - and no heat sinks on the 2130 drivers.

I'm really not sure why this is a problem. If you have evidence of heat causing issues with the electronics, please let us know and we'll take a look immediately. Life is hard enough as it is, though, so there's no need to create problems that don't exist.

If you want to add a fan, go for it. There are a few 5v options, as well as 24v options. I responded to one of your other threads with more information about that.

@mpirringer I find it humorous that you posted an article with this as the first line in the conclusion, "Although short fibre-reinforced composites offer better mechanical performance than their
unreinforced counterparts, there is still a certain gap between the mechanical properties of preimpregnated
fibre and conventionally manufactured fibre-reinforced polymer composites."

This is precisely the point I made. Furthermore, the research paper cited literally only tested CF Nylon for impact resistance, not tensile strength like my data

I spent nearly a decade doing injection molding. The fact that you suggest that "science" says otherwise about the strength of composite materials with chopped fibers means that you simply have zero experiential knowledge on the topic.
