Filament Spool Holder System that uses 608ZZ bearings.

This was inspired by the excellent work done by HugoHuge https://www.thingiverse.com/thing:3020026. However, it uses a different approach to a modular Filament Spool Holder that provides a much tighter design.

First you choose the mount that mates with your printer (these are called Bolts). The following is a list of "Bolts" currently available:

• Bolt-Neptune2 - ELEGOO Neptune 2, 3
• Bolt-Neptune3Pro - ELEGOO Neptune 3 Pro family
• Bolt-Creality - should fit Ender3, Ender3Pro, ...
• Bolt-2020 - generic mount that clamps into the overhead frame
• Bolt-Tron XY2 XY3

Next print your Nut or Knob to go with your Bolt (hint: they all match).

Choose the style of Spindle (and the corresponding frame) that you want:

Straight -- provides a very simple and very short frame;

Ridge -- spindle that has containing ridges on either end

Choose which length for the Frames/Spindle that you want to use. I have found that all of my spools do very well with the 75mm frame/spindle.

Assembly

Insert one 608ZZ bearing into each end of the Spindle. It will be a firm fit, but make sure that they are well nested. There will be a couple of millimeters of the bearing sticking out of the spindle.

Now insert each axel into a bearing on either end of the spindle. Take the entire spindle assembly and slide it into the slots on the ends of the frame.

All of the Frames use the same "plug" that inserts into an appropriate bolt. Take care to assure orientation of the bolt and frame are correct. You will notice on some of the bolts the end with the thread has an imprinted letter. Assure that the letter is upright and then glue the frame into place.

Insert the Bolt into your printer's mount and secure with Nut/Knob.

HISTORY

2023-02-22: add new Neptune3 Pro Bolt.

2021-09-17: Add new Bolt for the Tron XY2 and XY3

2021-09-12: Merge designs from thingiverse. Also rework those designs so they are much stiffer (no sagging).

2021-09-02: Updated spindles to have two slopes to the bevels to keep the spool centered.
