Cable organizer for Landroid style perimeter wire islands

This little cable organizer / helper is meant for easing up the process when forming Landroid style perimeter islands. As I’ve already set a basic perimeter wiring I’m using the helpers when adding islands to this existing system. 

In such case it's quite easy to thread the first wire through organizer piece and fix it to ground with a peg where the island’s junction will be located. At the other end a similarly set organizer is a good starting point for forming the island itself.

I recommend leaving enough reserve in cables at the boundary wire to locate the new wire connections far enough from the organizer piece. Wires can then be tightened by working towards the newly laid island and finally forming a reserve loop inside the island. By doing it that way you don’t have to touch so much to the original wiring.

Since the organizer can be split in two (there is slot for wedging with a flat blade screwdriver), also alterations to wiring (e.g. island removal or re-routing) can be done relatively easily without breaking or cutting any parts or wiring. The organizer also makes sure that the wires leave and arrive at junction points as parallel, thus they don't overlap each others. The organizer’s cable passage dimensions are 3.5 x 3.5 mm so most typical perimeter wire types should fit in.

As per organizer's construction, the pin which locks the halves together is slightly conical for sort of a pressure fit. Depending on your printed parts' final dimensions, joining the halves may need some additional force. Suitable pliers with parallel jaws can help with that. In case the pin fit is too tight or too lose, then experimenting with slicer setting “X-Y hole compensation” might help. 

Please see the enclosed photos for hints and suggestions.

PRINTING

Import the step file to slicer and apply “Split to Objects” command (in Orca). Lay both parts their flat sides to plate and locate them far enough from each other (for the “Print sequence” “By object” setting to work). 

The organizer’s halves are quite small and detailed so print them slowly and with solid walls/infill. Material should be resistant to outdoor usage, so I think PETG is a minimum. 

Also, some level of accuracy is needed for the parts to fit together. Related to that, my changes in (Orca) slicer settings were as follows:

Quality:

Seam position –> Random

Precise wall –> tick the box

Precise Z Height –> tick the box

Others:

Print sequence –> By object
