another one in my series of sinclair wallmounts (see also https://www.thingiverse.com/thing:3471201 for the original spectrum and https://www.thingiverse.com/thing:3471218 for the zx81).

print 2x the lower part and 1x the upper part - thats it.

cad design was made with solvespace - original .slvs sources included for your pleasure.

perhaps this mounts also fits for a spectrum 128 - but since I don't own one (yet...) I can't verify this.
