This OpenSCAD script will generate a simple one piece fixture to hold Wensi's PV layer's PV cell, PCB and supercap. This is using the slightly newer layout and SCAP propsed on the 17th August 2011

Author: Mark Gaffney
Version: 2.2
Date: 2011-09-16

Todo:
add thin infill for hollow sections to improve printability
make slide in PV version
make 2x corner 1 middle tab PV version
make screw post PCB version
make pin post PCB version
make mushroom post PCB version
move holes for SCAP pins (2x dia=0.6+blah separation=~10-blah dist_from_bottom~=2.5-blah dist_from_sides=5-blah) and PV wires to more logcal place, also change to square, triangle or teardrop shape for better printability
remember the SCAP is now a table profile with dia~=10.5

Warning:
there is no top part for this

Changes from previous versions:
2.2

• Change cutout for trapezoidal/pyramidal shape
  2.1
• Fixed some vlaues to place the support posts in corect location (up +1mm) scap leads Right +2mm
• increased post diameter for the two along one side slightly
  2.0
• New layout (PCB rotated 90Degrees) and larger SCAP
• change pcb_l 30->35 pcb_b 35->30
• change scap_l 23->20 scap_b 15->22 scap_h 5->10

0.8

• add thin infill for hollow sections to improve printability
  0.7
• moved entire structure above z=0 plane (no longer a destroyer of belts)
• added mouse ears
  0.6
• made thinner
• fixed incorrect measurements for PV panel
  0.5
• Added holes for wires between sections

0.4

• Removed plastic from centre of pv area to speed up print

0.3

• Fixed error with cutout translates due to misuse of separation and clearance variables
• Fixed error with second half of calculation of total _b using max() where I forgot to include separation

0.2

• Added support posts

0.1

• First attempt

1. Design and build prototype indoor energy harvesting electronics
2. Choose appropriate energy scavenger (aSi panel) and storage (supercap)
3. Print holder
4. Install and test
5. Re-iterate as required
