Grainlock Jig

GrainLock Jig – Secure Holder for Laser-Cut Faux Wood Graining BoardsTired of your 3mm laser-cut boards sliding around while you drag a rubber wood grainer or roll on paint for that perfect faux wood grain finish? The GrainLock Jig solves exactly that problem! Designed specifically for 3mm-thick boards (12" long × any width), this clever little 3D printed fixture bolts down solidly to your workbench and creates a precise, low-profile channel that sandwiches and grips your board without any movement. The holding lip is intentionally only 2mm tall — shorter than your 3mm board — so your grainer, roller, or comb glides smoothly right over the top for clean, jerk-free grain lines from end to end. Key Features:Super-stable hold → No more frustrating slips or uneven grain patternsWorks great with rubber wood grainers, paint rollers, combs, and other faux finishing toolsBolt-down design with countersunk holes (screws not included)Extra mounting hole at one end for flexible positioningComp
