AMS Lite Spool Adapter v3 (No Slip Grip)

This adapter allows larger inner-diameter spools (like Sunlu, Geeetech, Giantarm, and similar brands) to fit securely on the AMS Lite spool holder.

I've never uploaded previous versions, but this latest version introduces key improvements for better reliability and ease of use.

What’s New (v3)

• Improved flexibility - Easier installation and removal
• Enhanced fit tolerance - Adapts better to different spool variations
• Micro-texture / thread grip added - Prevents slipping on AMS Lite rubber rollers
• More consistent performance during long prints

Features

• Snap-fit design
• Secure hold without damaging spools
• Works with multiple filament brands with larger hubs
• Lightweight and fast to print
• Designed specifically for AMS Lite

Print Settings (Recommended)

• Layer height: 0.2 mm
• Walls: 2
• Infill: 15–20%
• Material: PLA or PETG is OK
• No supports needed

Compatibility

Tested with:

• Sunlu
• Geeetech
• Giantarm
• Anycubic
• Other oversized spool hubs

(Scaling may be required for uncommon spool dimensions)

Notes

• Designed for a tight friction fit
• The added internal texture helps lock onto the AMS Lite rubber rollers and reduce slipping
• If your printer is very dialed in, no post-processing should be needed

Tip

If your spool feels too tight:

• Slightly scale to 99–99.5%
• Or use PETG for better flex vs PLA
