SOVOL SV06 ADJUSTABLE BALL BEARING SPOOL HOLDER

 

I want to thank Rogerquin (rogerquin | Printables.com) for some nice feedback and pointers while I was designing this. He's got the best upgrades for the SV06 so go check his stuff out.

 

Foreword

I just go into detail about the parts and basic things to keep in mind while building and setting this up here. You don't have to read it, but it might help.

DISCLAIMER: This has been tested for small prints. I haven't used it for super tall and long prints. So you might want to keep an eye on your print, but it should be fine. Also, I am not linked to Sovol in any way.

 

Task:

 

I wanted to make a ball bearing spool holder for the SV06 that answered several problems:

  • It had to be adjustable to fit multiple spool widths
  • It had to be a steady fix
  • Include a filament guide 
  • Easily removable
  • Work for small and high prints
  • Be a very easy print, with only 4 ball bearings as extra cost.
  • Make it feel like it was part of the SV06 shape language with the bevels and typography.

 

Contents:

 

There are two main parts and a few smaller:

  1. One for the wider section of the gantry, consisting of two supports, one with the filament guide
  2. One for the thinner part, consisting of two supports
  3. 4 clips for the bearings
  4. 4 cylinder clips for improved steadyness

 

Print:

 

I printed this in PETG from ArianePlast (French company) but you can do it in whatever you want. Same goes for the settings, use what you're familiar with. Here's what I used in Prusaslicer:

  1.  0.2 layer height.
  2.  2 perimeters (You could do more I guess)
  3. 3 bottom layers & 5 top layers ( I just wanted the letters to come out nicely, we won't see the inside as much.
  4. I went for 10% Gyroid infill.
  5. I also used tree supports for the filament guide overhang because I haven't dialled in my filament yet. And because I wanted to try tree supports, I've never used them before. But if you've got your bridges sorted then don't waste your time with tree supports.
  6. I put 0 Infill in the cylinders, they don't really need it. 
  7. The way I arranged stuff here is just to show you, you're free to do it yourself.
  8. You will need to fix a model. Just do it and it'll print fine. 

This is definitely not optimal. But this is my first 3D printer and I still have a lot to learn.

Build:

 

_ You will need four 608 ball bearings for this. I used some really old and used skateboard bearings that my sibling had lying around. I cleaned them thoroughly with brake cleaner and made sure they turned smoothly, no friction. When I span them, they moved freely for a few seconds. I also think you should NOT oil or grease them. They should move as freely as possible so that the spool isn't hindered by them and grease just binds them up. Oil could be a decent option but you don't want that leaking all over your bed while you're printing. But feel free to experiment if you want.

_ Push the ball bearings onto the clips

_ The cylinders are a very tight fit into the supports. You can either print them at 99% or 98% ( I haven't tested this) or trim away a small 1 mm bevel of the edges to help wedge them in. It's what I did and I had no issues whatsoever. You will have to use a table to push them in fully. 

_Snap the clips with the bearing on in one the holes on the support. Flat side goes on the inside.  

_Press down firmly but gently on a table to make sure everything fits in place properly, you might need to readjust the bearing clips. 

_Make sure the bearings spin freely and that everything is straight. 

_Place the parts on the gantry. Make sure the two parts are as parallel as possible. They might not be 100%, depending on where you place it on the gantry. It'll still work just fine. Mine isn't perfectly parallel and it's been doing great.

_Feed filament through the guide, place the spool on the bearings, make sure everything moves smoothly and freely. We don't want any binding. 

_Good to go!

Check out the photos to see how and where I place things. It might be a bit of a tight fit for the filament guide if you decide to use 500g spools. So far, I've tested the Eryone tpu (Didn't use the guide), Amazon Basics pla and the ArianePlast petg. That's all I've tested since that is all I own.

End

Hope you find this useful. I had fun designing it and problem solving. There is always room for improvement, but for now, it'll stay as is. 

Post your makes as well.
