Lightweight Labware
Micron Extrusion Backers
Couldn't load pickup availability
Set of three extrusion backer plates for the 120mm Printers for Ants Micron. These backers are based on the Lightweight Labware / whoppingpochard extrusion-backer concept: add a matching metal strip opposite the linear rail to help reduce gantry movement from thermal expansion mismatch between rail and extrusion.
Why this part
- Built for the small Micron Classic / 120mm Micron frame, not the larger 180mm Micron+ layout.
- Useful when you are trying to keep the 1515 gantry behavior more consistent across cold-start and heat-soaked chamber conditions.
- Separate backer-only option if you do not need the bundled nut bars from the Micron 120 Titanium Backers and Nut Bars Set.
Included parts
- 3 × Micron 120 extrusion backer plates.
- Backer hardware is not included; pair with the Backers Screw Set if you need dedicated screws.
Fitment
- For Printers for Ants Micron 120 / Micron Classic builds using the 1515 extrusion frame.
- Pairs naturally with the Micron Motion Kit during a fresh gantry build or rebuild.
Gotchas
- This is not a full frame kit, motion kit, rail kit, screw kit, or nut-bar set.
- Do not buy this for a 180mm Micron+ build unless you have separately verified the backer lengths you need.
- Install backers opposite the relevant rail and check the Micron/backer documentation before final tightening.

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.
