Gotcha. Wish I had that template before I put wood screws in mine lmfao Do you have that in a to-scale pdf by chance?
Posts 182/183/192 have info on @Shootquinn printable design for the leadscrew nut bracket. Was just looking for it myself and had a heck of a time finding it in this thread!
Along these lines, I noticed thereās quite a bit of slop with the nut/leadscrew that came in the linear rail kit which might be a problem for many of my projects. Found a domestic supplier and ordered an anti-backlash nut from Zyltech in Houston; hopefully it is a drop-in replacement wrt mounting holes.

I put all of the parts I messed with in one place.

Iāve been laying low (busy enough with other projects and school) but you guys havenāt heard the last of me! Last I checked my sled even had printed gussets. Now I have a 20" x 20" printer so I was thinking of printing a whole sled.

Holy crap thatās a huge printer!!! I was trying to get mine working again, and it was cheaper to just buy a new one. So I got 2 Anet E10ās arriving Monday with about 12 rolls of PLA+ 
I do hope you print a sled, Iād LOVE to see that!
Thanks for the link! I saved it and will begin on it after I print all the E10 upgrades!

I have been looking at spindles, but havenāt decided on one yet. Though thatās kinda of the point, I want to be able to swap out and try different options.
My first attempt will be to use threaded inserts in the carriage and bolt on the mount (could bolt right though the carriage, if the bolt pattern doesnāt interfere with any of the hardware on the back). Alignment will probably be biggest issue. Easiest would probably be to create different shims to align spindles/routers with the center of the sled. Though bolting the whole z axis onto the sled might provide the greatest flexibility, it would also make it easier to use the original sled. The holes could be slotted for aligning the router with center.
Pretty sure I will have some time next week to start modeling all this in Fusion.
Templates are in the community garden page, under 2D CAD drawings. Unfortunately, because the sled and spine are so big they need a D sized page (24"x36") to fit them. I tried to fit the spine onto an 11" x 17" by itself but it would need to be split between two pages.
I (think) I noticed this as well, but only when I put a dial indicator on the carriage. I looked into one of those pre-loaded nuts as well, but at the time wasnāt sure if it was necessary. I havenāt heard any other reports of people having trouble with backlash, but as you mentioned, itās entirely possible you need better precision there than the typical end user.
Now that I would like to see! Also, thatās a pretty awesome printer. I think the Stratasys printers we have at work might be around that print volume, but I donāt remember off the top of my head.
Thanks for the Thingiverse link. Iām thinking I will pull the STL files and put them in the Community Garden page so theyāre all there. The only problem I could think of there is the guide block mounting holes on the carriage plate. Did that ever get fixed? I could always get that squared away real quick before uploading the STL.
Iām no fortune teller, but I see a lot of printing in your future! I still need to go through my pile oā filament and make it into useful things. Most of itās ABS, though, and Iām not sure if itās been exposed to too much moisture or not.
I like where youāre going with this. I had considered going that route after I assembled mine and realized that the dust chute gets locked into the sled as soon as the Z axis gets glued down. I donāt trust threaded inserts going into the edge of plywood, but if you made a base āplateā that solve that issue. Just have to make sure that clears the dust chute.
Although, somewhere around here I saw somebody mount the dust chute so it angles upwards, like at the 2 oāclock position. Might be a good idea as well.

I totally agree, I would not trust threaded inserts into the edge of plywood either. I am going to attempt putting the inserts into the sled and designing a base plate for the z axis that bolts to the sled but still allows dust collection though the bottom.
A little more progress! Only thing Iām waiting on now is my 3D printers to come in so I can print that leadscrew nut holder. And Iām pretty sure Iām going to print new router clamps too. Thanks @MeticulousMaynard for an awesome design, and top notch engineering!

with the maslow Z axis, you can load the nut in one direction (bungee or
equivalent) rather than going with a more complex way of dealing with backlash.

I think when I get done with this build, I may take it somewhere and have flames airbrushed on the sled and gussets. Make it look like itās moving faster!

I never fixed the block spacing issue because I had no confidence in the blocks I received.
Whatās the hole spacing supposed to be?
I can make that change and also put my F360 archive on thingiverse. Iām sure itās a mess though.

Iām not at my shop to verify the actual measurements for the hole spacing, but I can tell you if you look at the cad files in the Meticulous Z Axis download, those holes are spot on for the rail kit listed in the BOM. I used them as a template to drill my holes by hand, and they were perfect.
I whipped this up in like 10 minutes just from the cad files @MeticulousMaynard created.
I thought about rounding it all, and making it look sleek, but your design is already perfect so not trying to step on toes here at all.

My model dimensions match the ones in MeticulousSled_Nested.dxf. I may have bought or received the wrong blocks. This is what I meant about brain power though. 
Autodesk Fusion360 file added to thingiverse. License changed to public domain dedication (I hope this works with whatever license you selected, Bryan?)
Also I couldnāt find the front parts of the clamps in Fusion. No idea where those are. The STLs look good though.
Iām weak on documentation and follow-through. Luckily Bryan knocks those two out of the park!
edit: I donāt know if I said it or not but Iām supposed to be doing Chemistry homework on the weekends so I canāt spend mental horsepower trying to unravel Chinese supply chain / CAD version conflict issues. I KNOW BETTER, ASK ME HOW LOL

Oh ok! Perfect then! Your model SHOULD actually match the linear set listed in the BOM then. I say that because the link to the linear set in the BOM is what I purchased, and the holes lined up to the pillow blocks, the bearing blocks and the rod holders perfectly! I can at least verify that much for ya. However, Iām sure thereās still a chance that if you order from that link, that you might still get blocks that donāt line up right. call it a gut feeling.
And Iām now curious about the āhowā you know better than try to unravel the Chinese Supply chain / CAD version conflicts lmfao

At work we are constantly having stuff fabbed to old CAD models (even ones I swear that I deleted) and I swear that the Chinese have figured out (no matter what they send me) that I will never return anything. I throw the bad stuff straight into the garbage can so I donāt have to waste any time looking at it ever again. Probably should have tossed those blocks and we wouldnāt even be having this conversation!
The stuff at work is like a running joke, we will have a form block designed by one guy show up, and the part flat pattern that fits the other guys block get cut out a few hours later. Then when we want to make a change, the 2nd guys block will get cut out that time instead of the one we updated to get reworked. It is really great when that happens when Iām training someone, because those situations are so FUBAR that a new person would never be able to connect all the dots (people have a hard time believing that things can be that screwed up, like they canāt process it as true).

does anyone have a Fusion file with the updated style ring in it? everything that i can find on the community garden has the ring with the end L brackets facing in the wrong direction. the picture @MeticulousMaynard has on the community garden has the correct 3D ring in the picture. is there any way that can be shared? thank you.
@Daniel_Papesca: Iām confused. Are you referring to this link in the instructions? The ring is the same there as the one in the picture.
Is there a 360 archive file in the zip somewhere? Iām not seeing on in the directories.
