This is my model of a Filament Spool holder. This product will provide a stable and effective filament feed.

Hardware needed:

8x M3 Heat insert

8x M3x15mm screw

4x M5x12mm “minimum length”

Optional:

4x 625zz Bearing

Assembly:

I suggest ABS filament with 30% infill 5x walls 0.4 nozzle.

Print all Parts 1 on your favorite 3d Printer.

You may choose between parts 2.1 if you have 4x 625zz bearings.

Or 4x from parts 2.2 if you don't happen to have the bearings on hand.

Part 3.1 Is a larger fit.

Part 3.2 Is a tighter fit.

Step 1: Install the heat inserts 8x M3 on the main roller body “refer to photos for reference”.

Step 2: Install 4x M5x12mm "minimum length" screws on the 4 roller holders which will fit into the dented hole on the side and place rollers on.

Step 3: Secure the roller holders on the main body. Their position is labeled you will not see the position later on. Use this for 8x M3x15mm. Step 5: Insert the adjustment screw through the main right roller and fix it with the ring in its position.

Step 6: Any suggestions, comment, thought please feel free to contact me. The metric scale scale is for width adjustment.
