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

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

there is no top part for this

Changes from previous versions:

  • Change cutout for trapezoidal/pyramidal shape
  • 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
  • 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


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


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


  • 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


  • Added support posts


  • 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
