I wasn’t a fan of the rear-mount spool holder, so I designed two small parts that can be printed on the Zero. With just a couple of extra M3 screws and nuts, this relocates the spool to the top-front corner of the right-hand side panel. It reuses most of the existing hardware, requires no additional holes or tapping, works with the original PTFE tube and sensor-wire lengths, and doesn’t interfere with the door or cables.
Thanks, I added it to my collection. I would have liked to have seen inserts instead of nuts, but that’s fine.
Right now, I don’t have the spool holder installed…I’ve been printing straight out of a Sunlu S2.
I don’t have any inserts on hand, I usually just rely on the threads biting into the filament but I wanted to make sure this was strong… And I can lift the printer with the holder lol!

I’ve made a revision and will add a version for threaded inserts, question though, is leaving the M3 nut hex on the bottom reasonable? I don’t have any experience with inserts, would you trust them to hold 1KG on a lever arm?
It would have to rip the insert out to fail…having a nut under the insert might give it the pressure to pull the insert out.
I would just add both models, insert & no insert then let the user choose.
You might want to test it for a few weeks before you upload it.
I will add that for strengths sake, I would add the insert to the bottom side (where the nut is now) this way it wont have any chance to pull out the plastic if it was in the front.
EX. remove nut location & use insert there.
You would just have to explain to users that it bolts from the front into the rear instead of front to front.
This make any sense..??
Yeah it does make sense, thanks, I’ve updated the model and tested inserts, worked like a charm and is stronger than I was expecting, I always expected that I’d be able to rip them out with relative ease.
I will say original version is super strong, I can lift the printer with the spool holder, which is no mean feat given the weight of these things and even more impressive given its only held to the chassis with 2 M3 screws!
Cool, I’ll print it in the next few days just to have an option.
Thanks for listening to feedback.
No problems, I also forgot to mention that the updated model has larger recesses so washers can be used squish the plastic less.

Printed. I added 2 washers, other then that I used only the original screws.
I will say that the starting hole for the insert should have been a little bigger…maybe 0.3mm.
Haven’t tested yet, but I’ll assume it’s ok 
The inserts I have fit perfectly, but I did the white one on a Bambu A1 with PLA so I guess it didn’t shrink as much as ASA does.
It’s fine, not a big issue.. I just thought I’d mention it.
I used a pair of needle nose pliers to hold it down so it didn’t start crooked.
