Spool Clip W1 - Wing Grip Filament Clip, an Alternative for Spools Other Clips Slip On

An alternative spool clip for when the clip you already use doesn't hold well on your spool wall. It is NOT a universal clip - it was designed for, and tested on, a specific range of spools (listed below). If your current clip already works, keep using it.

HOW IT WORKS

• A middle cap sits over the spool rim, with a toothed pad pressing on the inside of the wall.
• Two long, flexible wings run along the rim on the outside and press back in at their tips.
• Each wing tip hooks over the rim to a small inner pad, so both ends pinch the wall like an open V.
• The long wings give it spring travel, so it grips both thin and thick walls instead of being too tight on one and loose on the other.
• The body follows the curve of the rim and sits flush, so it stays slim on the outside (box friendly).
• The filament tail presses into a groove with staggered bumps on the inner side.

FITS

• Spool wall thickness 1.8 to 2.9 mm (tested on 2.0, 2.1 and 2.8 mm walls). It does NOT fit 3.2 mm walls.
• Standard 1 kg spools with a side wall about 200 mm across. The top curve is cut for that rim size.
• It needs about 14 mm of bare wall above the filament, so it won't fit a completely full spool.
• 1.75 mm filament.

WHAT TO EXPECT

• Holds firmly on textured spool walls.
• On very smooth walls it stays put while printing, but a firm push can slide it along the rim.
• On thick (2.8 mm) walls it takes a bit of a push to fit on, then sits snug and flush.

PRINTING

• PETG recommended (it flexes without cracking). Not tested in PLA.
• Print as provided: flat side down, no supports, no brim.
• 0.2 mm layers, 4 walls, 100% infill.
• The 3MF is set up for the Anycubic Kobra X with PETG. Use the STL for any other printer.
• Clean off any PETG strings around the grip pads before use.

INSTALLING

• Push the clip straight down over the spool rim.
• Press the filament tail down into the groove.
