Handy Joints for 25 x 25 mm Timber (3 types)

thingiverse

Some handy 90 degree joiners for 25 x 25 mm planed timbers. Make square joints without skill or glue, easy to assemble and disassemble. They could probably be scaled a little bit to accept other sizes, although I've not tried. Three types are included: - Tee25x25 (a T-joint where one piece butts onto another) This joint requires a clearance hole through the running timber: the screw then taps into the endgrain of the butting timber. Note this item includes a modelled support to be knocked out prior to use. - TripleCorner25x25x25 (two pieces butt onto a third, all perpendicular) This joint has a single screw at a 45 degree angle, which must tighten into an edge of the running timber. Best to file a small flat here and drill a pilot hole (see image). The joint has grips hidden inside that retain the butting timbers when the screw is tightened. - Tee25toFace (a T-joint where one piece butts onto a decorative piece and the screws are hidden behind) The joint has grips hidden inside that retain the butting timber when the screws are tightened. SAFETY NOTICE: These joints are ok for light applications but are not as strong as proper joinery and must not be used where failure might cause injury.
