One of the sticky traps absorbed a mighty blow during the season and its ski-pole mount snapped off. Rather then rebuild the whole thing, I decided to just epoxy the pieces together and stick a reinforcing plate on the bottom.
I added a pair of screw holes to the OpenSCAD model and produced a projection of the bottom layer:
if (Layout == "Projection") {
projection(cut=true) {
Attachment();
Cap();
}
}
Which looked like this:
Cutting that shape from an adhesive sheet looks the same:
The somewhat raggedy large hole seems to come from OpenSCAD’s somewhat low-res SVG outline conversion.
Fill the broken part with epoxy:
Clamp it together on a plate to keep the bottom aligned:
Cut an acrylic baseplate:
Apply adhesive sheet to acrylic, stick it on the bottom of the cage, add a pair of stainless steel screws, and declare victory:
We’ll see how long that lasts out in the garden next year …

Maybe the SVG output polygonalization is driven by the same “number of facets” setting as the solid models are?
The SVG output follows my low-poly spec, but the laser cuttery includes additional jank.
Seen with cold eyes, I have the sickening suspicion Something Is Loose in the laser hardware, because it looks a lot like mechanical wobbulation at the vertices of those polygon sides. I’m in the middle of re-aligning the mirrors & suchlike, so maybe something will fall out of that mess.
Our AF2028-60 (twinsies?) arrived desperately needing mirror alignment, either due to travel or a bump it took while moving the beast downstairs. A daunting task for a newbie! First and second try were not so good. I’m pretty happy with the third try, and many fun projects have been made. So far the belts seem good; no major wobbles detected. I’m still a fan of the auto-focus, and I see they just updated it to a new method without the low-riding dongle (any time I buy tech you can expect an update shortly thereafter).
As clumsy as the autofocus is, it’s wonderful.
However much I would love to get rid of the “autofocus pen”, a mechanical switch seems more stable than any possible optical proximity sensor.
The angled red-dot laser pointer definitely needs major improvement. :mutter:
