Brick by Brick (B&M) Technic Compatible Replacement Parts — Non-LEGO Originals

Lost a piece from a B&M Brick by Brick Technic-compatible set? -> These are for you ! B&M's Brick by Brick range includes some parts that don't exist anywhere in the LEGO catalog — no BrickLink entry, no BrickOwl listing, nothing on Rebrickable. This collection covers some of those proprietary parts I was missing in my son's set, modelled from scratch based on original pieces CAD adjusted to match the Brick By Brick pieces . Parts included: Technic Liftarm Thick 1 x 5 with Alternating Holes — similar to LEGO 2391 but a non-LEGO size Technic Liftarm Thick 1 x 3 with Perpendicular Half Pins — B&M original, no LEGO equivalent Technic Pin with Perpendicular Axle Hole — B&M original, no LEGO equivalent Both STEP and STL provided. STEP recommended if you want to adjust tolerances in Fusion 360 or FreeCAD before printing. Printed successfully in ABS on a Qidi Q2 with active chamber. PLA should also work fine for light-duty use.
