* NOTE **
If you plan on enclosing your printer, and you have printed Z yokes, I suggest you obtain aluminum yokes or print replacements in high temp material. The washers are insufficient insulation when the printer is enclosed, and it will cause your yokes to soften, sag, and eventually fail.
Wade also noticed that the belt cutouts I introduced were in the corners without the cutouts for the idler and motor mounts. So I've fixed that with a new set called Belt Idler Pass Through and Mirror. YOu'll need two of each for a standard install. Again, check (like Wade) to make sure, since I don't have a 'standard' RailCore.
Wade noticed that I'd accidentally moved a pair of screw holes to 6.34 instead of 7.5. Fixed.
Steve London noticed that i FORGOT THE BELT CUTOUTS. Now find "BeltPass1" and "BeltPass2" which SHOULD fit the corners and pass the belts. Let me know if there are issues, as I don't have a normal belt path anywhere right now.
Tony and I have planned a cover for the Railcore 2 since its inception. We also wanted it to be the most customization friendly printer available for hacking... we joked about it being an engineering platform rather than a printer. The conflict between these two things hit us after the printer had already launched... how do you make a part that fits all of them if there are so many ways to configure them?
Well, at MRRF2019, Tony, Dave Randolph and I were chatting about covers, and Tony suddenly had a eureka moment where he figured out how to do .. well, this. He explained his idea, and since he'd already cut the parts for a top for my printer for me, I implemented his idea (with feedback from Tony, of course). There's one edge that's not implemented.. that's for you to customize with custom parts or selections of the components I've provided here.
See "How I designed this" for the links to the F360 archives.
You are going to want to print these parts out of plastic that will stand your hottest expected temperatures. To put this in perspective, in my tests, a 100C bed printing ASA for thirty minutes or so stabilized at 58C. This softened my belt retainers (PLA!) and my belts failed :D
Don't be Steve. Use higher temp plastic for your parts AND for this interface. PETG is good to 70C or so; it's what I used to print the parts.
Once this is installed, the top is just a box the same outside dimensions as your railcore, < 7mm thick walls, so 1/8, 3mm, 5mm, 1/4", 6mm, all should work fine.
And yes, I know there's a bunch of crud in the bottom of my printer. I work on it, ok? :D
