To replace a plywood fence for next year i created this modular pixel fence.  I wanted to accomplish the following goals with this:

1) Modular design that could fit on a standard size build plate (sadly too large to fit on my prusa mini)
2) Create a design that allows effects to flow between parts
3) Have the parts add up to 100 pixels (each circle is 25 lights)
4) Easily link together pieces to allow for assembling larger shapes.
5) Improve on the pixel hole design to make pushing pixels easier
6) provide a non-destructive way for mounting the props to their locations.


The holes have a slightly modified version of this test hole https://www.printables.com/model/722003-pixel-hole-test-print that allows you to turn the pixel in place and should friction fit the pixel rather than having to snap in.  I have not used this through a season so I am hoping these do not pop out over time.

The puzzle piece connections have two through holes for standard sized zip-ties to secure them in place with each other.

I've also made a bracket that just snaps over the puzzle pieces and secures with the same zip tie to allow screwing to wooden stakes.

I can provide any of the fusion360 files from these to allow anyone to design alternative mounting systems (one thought i had was making a camping stake adapter to essentially turn these into large peace stakes)

Nothing requires supports, suggest .2mm layer heights and 4 perimeters.  The full size with 4 connector circle takes about 100g.

Try out the test connector to make sure your printer doesn't have any tolerance issues.

Update 2/10/2024

I modified the connectors so they should flush up better.  The version I've uploaded have .001 offsets with the connectors which works perfectly fine on my A1, but with my .6 nozzle'd prusa mini I was not able to get a nice fit.  I've included 3 test connectors with different offsets as well as the f3d file that has some parameters for adjusting the fit.

One thing i probabably need to still do is add parameters for the zip tie holes because while my A1 can bridge these perfectly fine, my Prusa Mini is having a little issue getting the holes to work the same.
