Blurolls

Blurolls is a 3D printer motion-hardware shop running since 2016: Hiwin linear rails, belts, pulleys, machined and printed parts, full kits for self-build Voron, Prusa, and V-Core machines, and upgrade kits for consumer printers. It manufactures little of this itself — it assembles and resells — ships EU orders from a Poland warehouse, and trades at blurolls3d.com.

We list one Blurolls product: an X/Y linear rail upgrade for the Elegoo Neptune 3 and 4, at roughly 190 orders the most popular rail conversion in our Neptune survey. It replaces the V-wheel carriages and removes the play those wheels develop as they wear. It is a small operation — forums rate the kits themselves well but report missing hardware and slow replies from the seller.
