YAFSH (Yet Another Filament Spool Holder)
Description
Update: I developed this part using a software package that I use for my product machine shop. It is OneCNC XR4-Mill 3D.
Since this is my first post, any suggestions or comments that would help with future designs or postings are welcome.

This is not just yet-another spool holder. This is Amazing!
I tried many other configurations, but I like the no-messing-around direct feed and this design gets it done.
Thanks!
I had a difficult time with curling until I used a raft (I was trying to print raftless originally) and bumped the heated build platform up to 120C (I normally run at 105C). Because the raft is larger than the part, and because the part barely fits on my Thing-O-Matic, I did hit the limit switches but just let it keep printing anyway. The raft and higher temperature worked so well that it's difficult to get the raft off. I left most of it on if it didn't interfere with the dovetail or machine clamp.
If I were to print this again (which I probably will for the other side of my machine), I'd try raftless with HBP at 120C and extruder at 220C. I'm printing on a kapton covered HBP.
This was a great design. It's the first useful thing I've produced with my newly assembled Thing-O-matic.
The pieces fit together nicely after I filed down the teeth a bit. Nice and snug - solid. The inaugural run with the holder in place went smoothly.
I'm definitely looking forward to future builds - way less babysitting loose coils of filament!
Nice work.
Great first post.
Useful to include source, ie openscad,
Makes it much easier to derive from.
Would be great to see a photo of this built and attached as well.
But overall, great concept,
And welcome to te verse

I'm having one difficult time getting this to print..... To fit...
How in the world do you get it to 'just fit' on the building platform? I'm using a thing-o-matic with an HBP. I'm hitting ends, skipping steps, and having all sorts of general issues.
And my skipping steps is because I'm hitting the maximum travel limits... Not other issues.
This thing is TIGHT
