Length: 305, diameter: 35, wire diameter 0.3mm

The spring is relatively inexpensive, you need to cut it to the right length. 

Remove the plastic spring and insert the metal spring.

You need to insert it on the dust tube under the Dust protector part

Update  V3  01.03.2026:

• small design changes

• Revised dust extraction to minimize clogging of the springs

• Changes are possible using the already printed parts.

Update V2.1  19.02.2026:

Instructions:

(You can insert a metal spring instead of the PETG Springs in this step under the  top part (2) if you want)

Take a file or sandpaper and smooth the circled areas until they glide smoothly on the " Guide Rail" part

1. Insert the 3 printed springs into the designated guides. The springs are slightly longer and protrude slightly.

2. push the "Guide Rail" and the "Slide Bearing Top" part with the springs in the "Guide Rail Box part.

The scale on the guide rail points to the right.

Assembling it can be a bit fiddly because the springs build up a certain amount of preload.

3. Screw the parts together using the 3x M3x20mm cylinder head screws.

4.Slide the "End Stop (PETG)"  onto the guide rail as well and connect  one of the Tension Lever with a M6X35 Screw and a Nut

1. Slide the "Depth Stop Max" part onto the guide rail with the writing facing right.

2. Align the "Dust collector Box" parts with the three holes

3.Align the "Top Plate Dust Box" part on top and secure with 3x M3x20mm cylinder head screws

4.The optional printable TPU insert can now be slide into the guide.

1. make shure that the dust guide tube is flush with the housing.

1. Attach the "36mm Vacuum Connector" It should turn easily.

1. connect all together with 3x 3x M3X10-12mm counter sink or cylinder head  screws 

1. Insert a hexagonal M8 screw for the handle.

2.insert 2x M6 Nuts to the bottom

3.prepare 2x Tension Lever with 2x M6x45mm screw.

Screw the two Tension levers in on the right and left so that they rest without preload.

You can attach a handle to the M8 screw or print out the handle yourself.

Finish :)
