What are the proportions of a through mortise and tenon? · Hardware · basis: Xem Studio design — geometry computed in the generator from traditional proportions

Also called: through mortise and tenon, through tenon, mortise and tenon through, caja y espiga pasante, durchgehender Zapfen

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).
The tenon runs through the mortised member and shows on the far face, where it can be wedged.

Through mortise and tenon joint size chart

dimension	value
stock	20 × 20 mm square
parts	stile, rail
tenon	15 × 6.67 mm, 20 mm long (flush both faces)
assembles	the tenon passes through the stile
holds	racking; wedge it (see wedged through tenon) or pin it against pull-out
