Step 1 Two Spoolholder types

⬢

In this chapter, we will assemble the spoolholders, but before we proceed, note there are two types of the spoolholder.

Inspect the box your kit came in. If the large portion of the box is occupied by the rectangular black trays, you have the first version, the older vacuum-formed spoolholders.

⬢

1. Classic vacuum-formed spoolholder

If you have this version, continue to the following step Vacuum formed holder parts preparation

⬢2. New injection-molded spoolholder

This version comes in five packages inside a smaller box. If you have this version, skip to Injection molded spoolholder: parts preparation

Step 2 Vacuum formed holder parts preparation

⬢For the following steps, please prepare:

⬢Spoolholder base (1x)

⬢Foam pad (4x)

Step 3 Foam pads installation

⬢Turn the spoolholder base upside down.

⬢Peel off the yellow protective layer off the foam pads.

⬢Attach the four foam pads into the bottom corners of the spoolholder base.

Step 4 Rods, Bearings parts preparation

⬢For the following steps, please prepare:

⬢PTFE holder (1x)

⬢Shaft (2x)

⬢Plug (4x)

⬢Bearing (4x)

Step 5 Rods and bearings assembly

⬢Attach a bearing onto each end of both rods.

⬢Attach the plugs onto the rod ends to fix the bearings on each rod.

Step 6 Finishing up the Spoolholders (vac. form.)

⬢Attach the rods with bearings into the base part so that the bearings engage into the corresponding grooves on the base.

⬢There is a notch on the front part of the spoolholder.

⬢Attach the PTFE holder onto the notched front part of the spoolholder.

⬢Repeat the same steps to build the remaining spool holders until you finish all five.

Step 7 Injection molded spoolholder: parts preparation

If you have the injection-molded spoolholders instead, continue from here.

⬢If you already assembled your rectangular vacuum-formed spoolholders, please, skip to the next chapter.

Step 8 Injection molded holder parts preparation

⬢For the following steps, please prepare:

⬢スプールホルダーベース (4個)

⬢スプールホルダーガイド (1個)

⬢スプールホルダー車輪 (4個)

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

⬢フォームパッド（1枚）

⬢PTFE holder (1x)

Step 9 スプールホルダー部品の準備

⬢ベースパーツを1つ取り、写真のように配置します。

⬢2つの車輪をベースに挿入します。

⬢アセンブリの上に、別のベースパーツをかぶせます。

Step 10 スプールホルダーベースの組み立て

⬢両方のベースパーツを、一方が他方に完全にはまるまで押し合わせます。

⬢これらのパーツが正しく組み合わされていることを確認してください。

⬢スプールホルダーのもう片方の側にも同じ手順を繰り返し、2つのスプールホルダーを作ります。

Step 11 スプールホルダーレールを追加する

⬢フォームパッドシートを折り曲げて、個々のフォームパッドストリップを切り離します。

⬢スプールホルダー側面下部の内側開口部の内側に折り曲げ線があります。

⬢写真のように、開口部の内側にある折り曲げ線の真ん中にフォームパッドを貼り付けます。

Step 12 スプールホルダーの幅を調整する

⬢スプールホルダー側面のマークされた位置にパッドストリップを貼り付けます。

⬢フォームパッドストリップをスプールホルダーの反対側に取り付けます。

Step 13 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 14 Finishing up the Spoolholders (inj. mol.)

⬢サイドパーツをガイドパッドにスライドさせます。

⬢

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 15 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.
