How does a breadboard end let a panel move? · Hardware · basis: Xem Studio design — geometry computed in the generator from traditional proportions

Also called: breadboard end joint, breadboard end table top, breadboard end dimensions, testero, Hirnleiste, Hirnholzleiste

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

length: 160.0 mm
width: 200.0 mm
height: 10.0 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 cap across the end of a panel: the centre peg fixes it, the outer pegs sit in slots so the panel can move. For prints, the same trick lets a long part expand without cracking its frame.

Breadboard end size chart

dimension	value
stock	10 mm boards, 200 mm wide panel
parts	panel, breadboard, peg 1, peg 2, peg 3
tongue	3.33 × 10 mm
pegs	three Ø5; the outer holes in the tongue are slotted ±3 mm
assembles	end cap onto the tongue, pegs through
holds	the panel flat while letting it grow and shrink across its width
