==>. Corrected the model on 1/25/26 ==> ADDED A TEST BRACKET I recommend you try... if loose, try smaller by 1%, if too tight, increase by 1% !

1/25/2026 --- Ok, I went WILD !!! I have already TWO rolls on top of my Ender 3 V3 Plus... I guess that was not enough!!!

===>> I HAVE PUT A DUAL ROLL MOUNTS FOR BOTH TOP LEFT AND TOP RIGHT !! so the capacity at once is now 4 full rolls!! It should make easy to do pauses and swap colors even w/out CSF... mount ahead all your rolls, then just "retract" and "extrude" the new filaments for quick color swap!

===>> You do need to share the Run Out Sensor, BUT, when I have full rolls, I just put in it a piece of left over filament and don’t even bother running my filament through it if I know I do not have to worry about running out!

ENJOY !! ; )))

-------

===> I have also some model with NO LOGO... if you do not have CSF capacity or don’t want to waste the filament, the files

for the word "CREALITY" and the ’LOGO’ itself are there. Just print them in a different color and use CA glue to glue them!

Et Voila! beautified w/out wasting filament or CSF!

- There are 5 MODELS !?! Yep! I have put on mine 2 rolls on the top : ))

- there are 2 Front Facing Mount: one with the spool on the Left of the mount and the other one on the RIGHT of the mount!

- then I redid all the LEFT mount, RIGHT mount and kept the BACK mount as well obviously!

- The Run Out Sensor can be re-located to the top... make sure to buy or solder in some extension (I bought mine on AliExpress so I did not solder anything!)

- the original facing the back and I swapped it to face the front for my top mount spools!

- My spool came crashing down a few times when I was using high speed filament from the vibration! So I created a "C-clip Retainer" to stop this from happening!

- The light brackets are mounted on the back, you have the left and the right one to print... I have not tested them, I have mine already.

- He has the 608 BEARINGS for the SPOOL ROLLER -- The spool prints very well.. I had already 608 metal ones so I used those to reduce frictions... the ORIGINAL appears to have been a tad tight so the author added a second one LOOSER (print one, see if it fits, then print the other ones).

============ PRINTING TIPS

- PLA or PETG... just make them strong !

- with a nozzle of 0.4mm you can still set your settings at 0.3/0.6mm instead of 0.2/0.4.... TRY IT! goes much faster!

- I have since a nozzle of 0.6mm so my settings are 0.3/0.6mm but it goes even faster since the flow is more! Make sure to change your nozzle to for the flow in your Slicer!

-- 3 walls at 0.6 = 1.8mm thick

-- 4 top/bottom at 0.3 = 1.2mm thick (you can up to 5 to get also 1.8mm but 1.2 is strong enough!

- PRINTING DIRECTIONS MATTERS!

- you do need SUPPORTS -- I recommend to slice it first with the automated, see where they are and remove some by painting by hand if you want to!

- ORIENTATION:

- you need to think of the layers... do not print so the layers are along with the frame of the printer or there are too many chances for it to break! you need some angles like 30, 45, 60, 90 degrees, etc.

- depending on the model it can be on it’s side or front of back... of even at an angle like the author recommends 45 for the clamp that attach to the printer. -- I printed mine on it's back and increased total mm for walls and top/bottom so I have had no issues with them breaking!

============= FIXES

1/16/2026__ found that some of the models that I went back afterwards, I had downloaded a different Ender series than the 3 V3 Plus... so the bracket for some models did not fit!

-- So I made sure to work all in one day with the same Anchor Base and re-did them all !! That’s the V6 version that I am putting up!

==> I also included a "test bracket" so you can just print a 15mm wide mounting bracket to try first!! simply clip the top of the bracket in the back, then roll it down to clip the front anchor.

-- if a tad too tight, in the slicer go to re-size and add 1% and retest the TEST BRACKET

-- if too loose, go do to 99% of it’s size and recheck

============ The original back mount design was made by EBD Design Studio @EdinBearDragon at https://www.printaxxxx.com/model/864918-ender-3-v3-top-spool-holder-rear-facing

============ BONUS

THE TOP MOUNT SPOOLS ARE PERFECT IF YOU WANT TO TRY WITH THE SOFT ’TPU’ !! ; )

Make sure to relocate the sensor IF you want to use it... if not, take your filament straight down into the printer head... to avoid the printer to default because the Run Out Sensor has nothing in it, just place a piece of filament and leave it in there!

Also you may want to get a 0.8mm Nozzle as recommended in what I read so far (I have not tried it still!)
