Raspberry Pi B-PLUS B+ Model Bramble Rack Support and Connect

Rack Mount expandable/connectable holder designed for Raspberry Pi Model A - i simply had a designer add screw mounts to the previous design since the new Raspberry Pi B+ model does not have the long extending video plug that previously provided support, having been replaced by HDMI. Also includes top connector to keep 3 boards an equal distance apart on top.

Based on thing #177705

Comments welcome, i have not yet printed or tested this design yet.

Hoping to use this to mount 20+ RPI c
