Step 1 Injection molded holder parts preparation

⬢For the following steps, please prepare:

⬢Spool holder Base (4x)

⬢Spool holder Guide (1x)

⬢Spool holder Wheel (4x)

Wheels shipped after April 2024 are made of POM. We recommend using this version over the earlier models made from ABS.

⬢sheet of Foam Pads (1x)

⬢PTFE holder (1x)

Step 2 Base assembly (part 1)

⬢Take one Base part. Arrange it as seen in the picture.

⬢Insert two wheels into the Base.

⬢Cover the assembly with another Base part on top.

Step 3 Base assembly (part 2)

⬢Push both Base parts together until they fully engage one into the other.

⬢Verify the Base parts hold together properly.

⬢Repeat the same steps for the other side part of the spool holder, until you get two of these.

Step 4 Foam pads installation (part 1)

⬢Take the foam pad sheet. Bend it to separate the individual foam pad strips.

⬢There is a bending line inside the inner opening on the bottom of the spoolholder side part.

⬢Attach an individual foam pad strip onto the middle of the bending line inside the opening, as seen in the picture.

Step 5 Foam pads installation (part 2)

⬢Attach another four foam pad strips onto the marked positions on the bottom of the spool holder side part.

⬢Install another six foam pad strips onto the other side part of the spool holder.

Step 6 PTFE holder assembly

⬢Take the spoolholder Guide part. Hook the end of the PTFE holder onto the Guide

⬢Make sure the longer part of the PTFE holder is located at the narrower side of the Guide part.

⬢Push the PTFE holder down onto the Guide until it fully engages and locks in place.

Step 7 Finishing up the Spoolholders (inj. mol.)

⬢Slide the side parts onto the Guide part.

⬢

Repeat the same steps for the remaining Spool holders, until you assemble all five.

(Don't forget about the foam pads on the bottom!)

Step 8 Joining the Spoolholder Guides

⬢

There are protrusions on each side of the Guide part.

⬢Using these protrusions, the Guide parts can be joined together. To join them together, simply tilt in the Guide parts one into the other until the protrusions click in.

⬢The Guides can be joined together in form of a straight line.

⬢Or, if you flip one of the Guides around, they can be joined in an arc pattern. This is handy to form an arc of spool holders around the Buffer so that each filament path is as straight as possible.

Step 9 Injection molded spoolholder: parts preparation

⬢Congratulations! You successfully assembled all five spool holders.

⬢Now, continue in the chapter: 4. Preparing the assembly
