Geeetech M1 / M1S Spool Holder Adapter 1 kg Spool

This spool holder adapter is designed specifically for the Geeetech M1 and M1S to offset the spool position and allow the use of standard 1 kg filament spools, which do not fit well on the stock holder without colliding with the USB- and Power-Connectors.

By shifting the spool backward, this adapter improves clearance, reduces rubbing on the frame, and provides smoother filament feeding.

Features

• Compatible with Geeetech M1 and M1S
• Reuses the original spool holder for less material use
• Supports standard 1 kg filament spools
• Simple press-fit / bolt-on installation (no permanent modifications)
• Improves filament flow and reduces drag
• Compact and sturdy design with built in support structures

Installation

1. Use some needle nose pliers to remove the 4 support pieces
2. Remove the original spool holder.
3. Attach this adapter to the existing mounting and turn it counter clockwise until it snaps in place
4. Insert the original spool holder to the adapter and twist it, until it snaps in place

Recommended Print Settings

I've provided a Orca Slicer profile and to be used directly on the M1 / M1S with PLA - just load it and fire it up - a profile for Bambu Studio alswell as the raw model geometry is also provided.

• Material: PLA is sufficient
• Layer Height: 0,2 mm
• Infill: 10 % cross hatch or gyroid
• Perimeters: 3 walls
• Top/Bottom Layers: 4 - 5
• Orientation: Print flat on the build plate

Supports: are not required

The supports are built in directly in CAD - the slicer will probably warn you, that the model has floating regions - this is intended, since the support structure will have 0,2 mm spacing and "float", so they don't fuze to the model. If you want an ultra clean look, you can load the raw geometry, disable the support bodies and use your own preferred support method.
