Black Bed-Leveling Die Springs - Light-Load 8x4x20mm | Voron / Printers for Ants / Ender
Couldn't load pickup availability
The yellow spring spec — finally in black.
The spring your printer wants for bed leveling isn't defined by its color — it's defined by its load class. Industrial die springs are color-coded by rated force, and the correct class for a heated print bed is the light-load spring — the one normally sold in yellow. Too stiff and it fights your leveling screws; too soft (like the springs in your kit) and your bed drifts out of level after every few prints.
We had these printer-grade light-load die springs custom-manufactured in black — identical spec, blacked-out finish — so your stealth build stays stealth. Same engineering. No yellow pop under the bed.
Why this is an upgrade, not just a color swap
- Consistent, repeatable tension. Engineered die springs hold preload across hundreds of print hours; soft stock springs lose tension fast.
- Holds your bed level. A firm, defined spring rate resists the vibration that walks leveling knobs loose — so you re-level far less often.
- Doesn't sag under heat. Heat-rated spring steel holds its force at bed temps where cheap springs relax and compress permanently.
- Flat, ground ends. Square-ground faces seat flush and load the bed at a true 90° — no rocking, no shift between prints.

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.
