5mm D-Cut Shaft — every length: Voron 2.4 Z, Micron Z, V0 Belted Z, LH Stinger, ERCF v1.1 / v2 / v3

$2.99
Shipping calculated at checkout.
Length: 45mm

Hardened 5mm D-cut shafts for pulleys, gears, belted Z drives and ERCF gear rows: a ground flat the full length so the grub screw seats on steel instead of chewing a round shaft. Every length we cut, in one place. Pick by what it fits; the length is in the name.

Which length

  • 60mm — Voron 2.4 Z drive, four per printer. The four-shaft set is the full printer.
  • 50mm — Micron Z (the BOM's "5x47-50mm shaft, grind flat", four per printer; set here) and the LH Stinger Z stack.
  • 72mm — LH Stinger Z stack, and the V0.1 Belted Z Drive mod, which calls for 72mm over 70mm to leave room for a metal 80T gear.
  • 45mm — general stock. No current printer BOM we know of calls for it; it is the standard short length for a pulley or idler axle.

ERCF gear shafts

One shaft runs the whole gate row. The two ERCF generations use different lengths for the same gate count because v2/v3 filament blocks are 2mm wider than v1.1's. Buy the row that matches your build.

Gates ERCF v2 / v3 ERCF v1.1
4 164mm 159mm
6 210mm 201mm
8 256mm —
9 279mm 269mm
12 348mm 337mm

Lengths are the official BOM formulas (v2/v3: 72 + 23 per gate; v1.1: 70 + 21 per gate plus a 5mm spacer per three). The v2/v3 rows are also listed as ERCF v2 / v3 D-Cut Gear Shaft and the v1.1 rows as ERCF v1.1 D-Cut Gear Shaft; same shafts, same prices, same stock.

Specifications

  • Diameter: 5mm, −0.02 / −0.03 (supplier drawing in the photos).
  • Flat: 4.3mm across the flat (0.7mm deep), full length.
  • Material: stainless steel, bright finish, not hardened. Exception: the four ERCF v1.1 lengths (159 / 201 / 269 / 337) are 12L15 free-cutting steel from the 2021 batch, so keep a film of oil on those.
  • Lengths: 45 · 50 · 60 · 72 · 159 · 164 · 201 · 210 · 256 · 269 · 279 · 337 · 348mm.

What it is not

  • Not a smooth linear rod: the flat is the point. The v1.1 lengths are plain steel; everything else is stainless.
  • Not an 8mm rod. If your bearing bore is 8mm you want the linear rods.

Shipping:

US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.

International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.

I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or returned, I will not be responsible for returning your shipping cost.

If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.

Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
