Introduction: 3D Printer Filament Bobbin Holder - Version 2.0

About: Welcome to my Instructables channel where I'll share my wacky and unique creations that hopefully others find useful, or better yet, inspire an evolution of even better ideas!

UPDATE 10 JULY 2020: I included a step (and .STL file) at the end for 75mm wide bobbins. (PRUSA Brand)

UPDATE 28 JULY 2020: I included a step (and .STL file) at the end for 60mm wide bobbins. (eSUN Brand)


So version 1.0 (PVC Bobbin Holder) ended up not working well, so behold version 2.0.

All parts can be printed without support and require no post processing.

NOTE: This is sized for a 65mm wide bobbin.


  1. Qty 2 (sold by the pair): Sliding Glass Door Rollers
  2. Qty 4 1/4" 1" Long Screws (Thread and head style not important)
  3. Qty 4 1/4" Nuts
  4. Qty 4 1/4" Washers


  1. 3D Printer
  2. Wrench
  3. Screwdriver

Step 1: 3D Print the 4 Parts

I've included the Fusion 360 files in case you want to make any changes.

Print settings for Ender 5 Pro (using Cura):

  1. 1.75mm PLA (Overture Brand)
  2. 0.12 mm layers 25% infill
  3. 0.8mm wall thickness
  4. 0.5mm top/bottom
  5. 205C and 55C temps
  6. No supports
  7. 100mm/sec speed
  8. Hairspray

Step 2: Assembly Step #1

Gather all the parts.

Step 3: Assembly Step #2

Insert one of the small 3D printed parts into the two larger parts.

Step 4: Assembly Step #3

Install the second smaller part.

Step 5: Assembly Step #4

Attach the rollers with the 1/4" hardware as shown above. (Washer goes under the nut.) Hand tight and then an additional 1/4 turn to be tight.

Step 6: Finished

Thanks for taking the time to read through my Instructable. Please send me any questions or comments you might have. I try to answer them all. Stay safe and healthy! Happy Printing!

I've only been using version 2.0 for a few days, but its much better than version 1.0 so far. Absolutely silent (where version 1.0 was constantly making noises). And no "escapes" (yet). I'll update if anything changes.

Step 7: 75mm Wide Bobbin

I recently purchased some filament other than the Overture brand. Found out that the PRUSA brand uses a 75mm wide bobbin. Please see below .STL file for the cross pieces if you are using filament with that size bobbin. No other changes are needed. Just swap over to these which are 10mm wider.

Step 8: 60mm Wide Bobbin

Update 28 July 2020. Same as for the 75mm. Just swap out these parts (.STL attached) if your bobbin is 60mm wide.
