A4T Hardware Kit

Details

Every screw, nut, heatset insert, standoff and pin from the A4T BOM, for an A4T on an Xol carriage, in A2 stainless. Built from the official A4T and Xol carriage BOMs, with the extruder screws for all three common extruders in the bag so you don't have to pick before you order.

Screws

• 10× M3x8 socket head (DIN 912)
• 2× M3x50 socket head — bottom cowling
• 2× M3x6 button head (ISO 7380) — hotend adapter on the carriage
• 2× M3x16, 2× M3x12 and 1× M3x20 — extruder mount, whichever you run

Nuts and washers

• 5× M3 square nut (DIN 562)
• 5× M3 hex nut
• 2× M3 washer (DIN 9021)

The rest

• 8× M3 heatset insert, Voron spec 5 × 4 mm
• 2× 3x30 dowel pin and 2× metal tube — belt mount
• 2× M3x20 standoff — toolhead board
• 2× cable tie

Fits the WW-BMG, the Sherpa-Mini and the Wrist-Watch G2: all three extruder screw lengths are in the bag.

The A4T is designed by DW-Tas (github.com/Armchair-Heavy-Industries/A4T). 10% of every A4T kit I sell goes to him to support the project — printed parts and hardware alike.

Not included: fans, LEDs, hotend, extruder, toolhead board and printed parts. See below for where to get them.

Made to order and packed by hand — allow 1 to 2 weeks.

A4T set: 5% off. Buy this kit together with 2× GDSTIME 4010 blower and the Delta 2510 hotend fan and all four get 5% off, applied automatically in the cart.
