Universal Roller Shade Pin-End L Bracket
L-shaped replacement bracket for the idler (pin) end of a roller shade, replacing cracked or discontinued brand brackets without changing the tube ends. A closed tapered slot (4.6 mm at the bottom widening to 10.8 mm at the top) self-seats any round spring-loaded idler pin from 5 to 10 mm diameter; the pin axis stands 30 mm off the wall plate so tubes up to 38 mm OD clear it. Four 4.5 x 14 mm vertical slots take #8 pan-head screws for outside mount (wall leg) or inside mount (pin leg) and give 10 mm of height adjustment to level against your existing clutch bracket. 60 x 24 x 56 mm, 4 mm plates with a 6 mm corner web, printed standing so load runs along the layers.
Slotted Awning Window Scissor Stay Arm
A replacement arm for the flat scissor-stay linkage inside older awning windows, where cracked OEM arms are no longer sold. It is a 158 x 18 x 6 mm bar with a fixed 5.5 mm M5 pivot hole and a raised thrust pad at one end. Two 5.5 mm wide slots let you set the other pivots where your old arm had them: the middle slot runs 52–78 mm from the pivot and the end slot runs 119–143 mm. Measure your old arm before ordering, then fit it with M5 bolts, washers and nylock nuts.
Slotted Hook Window Sash Lift
A replacement hook-style lift for the bottom rail of a double-hung window. It is 60 mm wide, 45 mm tall and projects 26 mm, with a 16 x 10 mm finger pocket under the hook. Two 4.5 mm slots fit #6 (3.5 mm) or M4 pan-head screws at any spacing from 30 to 44 mm, so it lines up with the old screw holes after the original cast lift breaks.
Compliant Spring-Bolt Sash Tilt Latch
This one-piece surface-mount latch replaces cracked tilt latches on vinyl single- and double-hung sashes, and it also works as a spring catch for gates and cabinets. A 10 mm ramped bolt sticks out 5 mm and pulls back 6.5 mm by its thumb tab. A printed serpentine spring with nine 1.2 mm beams pushes it back out, so there is no metal spring to source. The 68 x 31 x 8.4 mm housing mounts with two 4.5 mm holes for #6/#8 pan-head screws or M4.
Twin-Horn Blind Cord Safety Cleat
A 80 x 16 x 12 mm twin-horn cleat that screws beside a window frame with two #6 wood screws (4.5 mm clearance holes with counterbored heads), so looped blind and curtain cords can be wound up out of a child's reach. It replaces the small stamped cleats that go missing or snap. Each horn leaves a 6 mm tapered gap for the cord to wrap into.
Sliding Window Track Vent Stop Clamp
A C-clamp block that sits over the raised rail of a sliding window or patio-door track. An M5 bolt in a captured nut locks it in place, so the sash can only open to a set ventilation gap. It is 56 x 28 x 18 mm, has a 13 mm throat that fits rails 2–11 mm thick, uses an 8 mm across-flats drop-in M5 nut slot, and the solid 21 mm jaw works as the stop face.
Casement Window Crank Handle
Replacement folding-style crank handle for casement and awning window operators whose original plastic handle has stripped or gone missing — the mechanism outlives the handle and the OEM part is usually only sold as a whole $40–80 operator. The 26 mm OD hub has a 9.6 mm through bore and two opposed M4 heat-set inserts (5.5 mm bores) so set screws grip any splined, D or round operator stub from 5 to 9.5 mm; 80 mm crank throw, 16 mm dia grip, 105 mm long overall, 44 mm tall. Print in PETG or ASA if the window gets direct sun.
Print-In-Place Window Restrictor Stay
A print-in-place sliding restrictor stay that limits how far a window sash or door can open: a 136 x 28 x 8 mm slotted arm with a captive Ø10 mm sliding post trapped in an internal T-slot at 0.4 mm clearance, giving 85 mm of travel (screw spacing 58 mm closed, 101 mm at the hard stop). Both mount holes are 4.5 mm for a #8 wood screw or M4, and an integral 1.8 mm leaf-spring detent snaps over the flange near the end of the slot so the window is held at the restricted opening instead of drifting shut.
