Replace the Ultimaker 3 clamp clip

The clamp clips lock each Bowden tube in place. Without the clamp clips, the tube coupling collets which hold Bowden tubes can move up and down during printing, especially when retracting. This can negatively impact print quality.

If the clamp clip breaks or gets lost, you need to replace it. The following steps describe how to correctly install the clamp clip. These instructions are the same for the clamp clips at the print head and the feeder.

Caution: Before you start, turn off the printer or ensure the Ultimaker 3 cannot accept new print jobs through the Digital Factory.

1. Move print head

2. Remove clip

Manually place the print head in the front-right corner.

Tip: This is simply for easier access to the print head clamp clip. Not required when replacing the feeder's clamp clip.

Use your fingernail to remove the old clamp clip from the print head or feeder.

1. Insert Bowden tube

2. Place new clip

Make sure the Bowden tube is still fully inserted into the tube coupling collet. Firmly push the tube into the feeder or print head, while keeping the tube coupling collet down.

Keep the Bowden tube in position and place the new clamp clip around the tube coupling collet to lock the Bowden tube in place.
