LDO Post-Install Drop-In M3 Nuts for European Standard 1515 Extrusion
Couldn't load pickup availability
Post-install M3 slide-in nuts for LDO-style European-standard 1515 extrusion. This 20-piece LDO pack lets you add M3 mounting points after a compact printer frame is already assembled, without tearing the frame back apart.
Why use these instead of preload nuts?
- Designed to slide/roll into 1515 aluminum extrusion after assembly, so a missed nut does not turn into a rebuild.
- Threaded for M3 fasteners and sold as a 20-piece pack for Voron V0 / V0.1 / V0.2 and other 1515-frame printer work.
- Best fit is LDO / Misumi-style European 1515 profile; West3D and KB-3D both list this LDO part specifically for LDO 1515 extrusions.
Specifications
- Thread: M3
- Profile: European-standard / LDO-style 1515 aluminum extrusion
- Install style: post-assembly slide-in / roll-in T-slot nut
- Quantity: 20 nuts
- Brand: LDO
Fitment notes
- Use these when adding panels, lighting, Nevermore mounts, toolhead accessories, or other M3-mounted parts to an already-built 1515 frame.
- For printed nut retainers that keep regular M3 nuts from sliding inside LDO-style 1515 extrusion, see No-Drop Nuts for European Standard 1515 Extrusion.
- If you are working with MakerBeamXL/OpenBeam-style 1515 extrusion instead, use the MakerBeam XL T-Nut instead of assuming cross-fit.
Gotchas
- Not universal 1515 hardware. West3D states these only work in LDO frames, and dfh customer reviews report non-fit on MakerBeamXL, generic AliExpress, and some Siboor extrusions.
- These are loose metal nuts, not printed retainers; if you want nut-positioning support, pair them with a compatible no-drop holder.

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 rerturned, I will not be responsible for rerturning 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.
