What is an ari kake joint? · Hardware · basis: Xem Studio design — geometry computed in the generator from traditional proportions

Also called: ari kake, 蟻掛け, dovetail housing beam, dovetail beam joint, japanese beam to girder joint, junta cola de milano viga, Schwalbenschwanz Balkenanschluss

Exact dimensions. True size, with no printing tolerance added.

length: 80.0 mm
width: 80.0 mm
height: 20.0 mm

Notes

Woodworking joint drawn for 3D printing: the parts lock together by shape, so a print can be joined without glue or screws. Drawn at true size with the parts line to line (zero gap) in their assembled position — add your printer's fit allowance to the mating faces (your AI or slicer can do this).
A beam end dovetailed into the side of a girder, dropped in from above — Japanese framing's standard beam-to-girder joint.

Ari kake size chart

dimension	value
stock	20 × 20 mm square
parts	girder, beam
dovetail	8 → 13 mm, 10 mm deep, upper 15 mm of the beam
