MFS Sovol SV08

Works great, just a tiny thing that I realized in the BOM: it says, you need 11 m5 screws but in fact, you need 20, one for each of the 20 bearings. The m5 t-nut did not fit on my case, I just used an m3 t-nut and an m3 screw with a few washers that where flying around on my desk. Works great for plastic filament rolls but the paper ones are often deformed which leads to a waggy run (but still works). Overall great design!

i printed this and i want to get the enclosure, but is the compatible with the enclosure or any of the top hats

Before I get into this build, here is my "goal" and I would love to hear feedback from those who are running this system.

Down the road I will be adding tool changer functionality, but short term, I want to fully enclose my printer with these spools inside the lid. The idea is to use the ambient temp from the chamber to maintain the filament dryness while printing and have optimal filament conditions already inside the enclosure for each of the tool heads to use.

First question is do these sides stay inside the outer plane of the printer?

Second question would be the umbilical.... I see it gets moved, but I haven't found a picture of where it gets moved to. It would ideally stay inside the enclosure as well, but can be remixed if that isn't already the case.

Thanks for the awesome design! Ended up designing and printing my own rods. It’ll be perfect for the toolchanger build.

I just assembled mine and it looks like it will work great! I don't have anything to print right now, but I did a QGL to see if it could reach everywhere and it had no issues, it even looks like the umbilical is held in a better position than the default configuration.

I didn't have to make the cable for the filament runout sensor longer though, it goes straight out of the hole, behind the gantry, then up to the top guide. It can easily reach all spools and I even have a lot of slack. Running it up the default channel at the rear right would look a lot better though so I'll probably change my configuration since swapping spools takes less effort than changing the runout sensor position, keeping it in the same place also keeps the umbilical in the same position so you don't have to worry about that if you know that position works. It would probably also work better with an enclosure since one hole for the reverse bowden would be all you'd need, which would making the enclosure airtight easier.

The only small downside i experienced is that the threaded inserts went in too easily, It's on there but i feel like they might slip out if I bump it on accident for example. The side mounts were also slightly too narrow for me, I made it fit eventually though. but I changed the file to be compatible with 22mm dowels since it's all I could find, so that might be an error in my modeling or not quite accurate dimensional accuracy on my printer.

Besides that I quickly realized that this model is somewhat overcomplicated, i feel like it would also work if there were just two bars on bearings, I don't see what the functionality of the snappable spool holders are, but I might be missing something. Please LMK.

Either way this is a super cool model, even if the snappable parts don't add functionality, I think it looks awesome and is worth it for the looks alone, 10/10 would recommend.

edit: I feel like this would be ideal for a toolchanger though. (edited)

Where can you order the longer cord for the filament sensor?

I used some standard 3/4" EMT I had with a small shim adapter and it works great! I did have to special order the bearings as I only typically have 608s on hand, but it makes the printer's footprint so much more manageable, thanks!

Do you by chance have a link to where I can find the rods? I've tried searching online and the only thing close to them cost over $100.

Does this work with the enclosure?

This seems to be a really well designed system, congratulations!
