FYI I used onlinemetals.com for getting the MIC6 aluminum plate. Wasn't the cheapest but it was to my spec. So far most sites I went to in the US only take dimensions in inches so I had to get my build plate cut to 13" and I'll build around that size. I used had them cut it from their .25 inch stock which is a little over 6mm.

And thanks for the list, you had a couple of vendors I hadn't ran across. McMasters-Carr has also the added benefit that all their products now have a 3D model you can download and include in the design projects.

Yeah, I wasn't able to get mine cut exactly either since industrial sites like this seem to only use inches. I assume that there is some room in the bed design to get the closest fit possible. My 415x415 print area says I need a 440x440 bed plate. That would mean that there is already some amount of gap in the frame tolerance for this. In addition, the bed square that the bed plate mounts to sits under and there seems to be enough clearance. The thickness probably also doesn't matter either for the same reason.

Same when it comes to the print surface. Most places online only give 410x410, so that's the size of my print surface. I might need to make some slight adjustments in the firmware to make that work (and maybe move the endstop out 5mm), but it should be doable.

Mcmaster-Carr seems like a good resource to get decent quality bolts and I'll probably check them out in the future. What's their shipping speed and cost like? Finding the random screw brands on Amazon has at least the benefit of usually arriving in 2 days, sometimes in hours.

Not sure on the turn around time for McMasters-Carr but their prices usually seems a little more and I usually can find places to beat their price. They do have hard to find items and when your crafting a new design it really is nice that they have downloadable models of all their products. I'm not sure how you can get one but they have a really thick catalog which also include part designs and specifications. I think you have to order a lot from them before they send one to you but it is also another resource.

Would it benefit us to have a public github repo in table format for all the parts with links to suppliers that we could all update, etc? In short, I started ordering my parts this week and that entailed - as we all know - reading this thread and searching for each item. I started an Excel document and have finished it for every single part with quantity needed (415x415x440 build), quantity needed to order, cost of the part, and link to a supplier. I was doing this so I could lump order parts to reduce shipping. A lot of it though, I went the Amazon route - it will be a bit higher cost - but trying to buy from so many of the stores on Aliexpress the shipping costs ate up the savings. Anyway, just trying to think of a way where we could crowd source these lists and make it more accessible. I am also not against the lists if they were affiliate links for @MirageC so it would fund additional research. Thoughts?

Yeah it's great you can import their parts in. Though generally with 3d printing it isn't quite precise enough where the difference between their parts and some random parts would cause things not to fit in my experience. Most of the bolts and nuts I ordered ended up being uxcell branded which worked fine.

Yeah a repo could be helpful to have a list of links to all the materials. Granted with Amazon at least, some parts get discontinued or run out of stock so there would be some long term maintenance required. On top of that, other configurations would change the BOM thus changing the required amount of bolts etc. No enclosure vs enclosed vs heated vs soundproof will also have different requirements.

I'm fairly against Aliexpress just because it takes so long to get the orders. The best way would be to as you said, bulk order from Amazon and just select an Amazon day so they can ship them in as few packages as possible. You're still going to get cheap parts from China, just pre-imported that arrive in less than a week. In my case I unfortunately forgot quite a few random bits, or was short a few pieces. I bet my USPS mail person hates me due to the amount of random packages I've had streaming in each day. I found especially with bolts and nuts I seemed to be low, despite counting out the amount I ordered and the amount it said to order in the BOM.

Other things not mentioned are the tools required. A drill, dremel and deburring tool are super important for this build. I learned the hard way I needed to just buy a drill when I got to drilling the aluminum plate. I've been using an impact driver whenever I needed to drill in the past (impact setting off) but that didn't work great for metal as well as its worked for plastic in the past. The dremel of all things I used to make one of my ball screws thinner at the top, by sanding it down. The bottom was also too thick but I got it most of the way in and it's in there probably for good unless I cut the bearing off or bought a vice. You'll need a wire stripper and crimper, some sort of connectors ie dupont, crimp on connectors for the PSU and SSR, allen keys, a square, ruler, calipers, etc.

I agree having a list of very helpful tools would be good to list. I have probably most of the tools I would need to build my printer except a good way to accurately cut the extrusion so I ordered precut to the sized required in the Frame Calculator sheet. Another one to add to the list is drilling gigs for the 2020 and 3030 and a set of metric taps.
