A laser cut clip for acrylic that allows self-locking 90 degree joints between parts using no additional hardware. Included are a profile to use in your own projects, and a box that demonstrates 3 configurations. Further details are also at: www.def-proc.co.uk/b/mybikInclude to laser profile in Elastic-Clip.svg in your own projects. Matches with a 10mm long slot in 3mm thick material.Cut out Clip-Box.svg and cut from 3mm acrylic as a practical example of the clips in use. Build instructions for the clip box are the same as for the Clip-R-Pi case that I also developed. Instructions are available at <a href"www.def-proc.co.uk/p/clip-r-pi/build">http://www.def-proc.co.uk/p/clip-r-pi/build">www.def-proc.co.uk/p/clip-r-pi/build (minus the bit about the Raspberry Pi!)Someone mentioned to me that the SVG files weren't any good for them, so I've added DXF and EPS too.
