How to Use:

1. Download the "Adapter for 250g SainSmart 154mm Spools" file and the “SainSmart Clips” file.
 

2. Print one set of 6 clips. I chose the following settings: 

• 0.2mm layer height
• 3 walls
• Infill won't matter due to the 3 walls and relative part size
• 3 top and 3 bottom shells

3. Print 2 "Adapter for 250g SainSmart 154mm Spools". I chose the following settings: 

• 0.2mm layer height
• 2 walls
• 16% honeycomb infill
• 3 top and 3 bottom shells
• Normal(auto) supports, Style: Snug, Threshold Angle 30deg

Assembly:

The clips provided are unique to this spool adapter and, unlike the original model, there are 2 unique sets of clips, one for each side. This is due to the SainSmart spools having one side thicker than the other. When printed, the top row of clips are narrow and the bottom row are the wide version.

1. Remove the support material.
2. Identify the thinner side of the spool and place it in the spool in the adapter
3. Grab the narrow set of clips and slide in 3 clips to retain the spool. All 3 clips are unique and created this way to snap into place when fully inserted. I added photos, so you can see how two of the clips have a relief cut to allow them to fit near their respective surrounding “pillar” in the ring, while the remaining clip is flat and fits in the slot that has an opening in the ring.
4. Repeat this for the other side using the remaining clips.

Notes:

I added some Fusion 360 and STEP files if you would like to use them to modify further.
