Rain Catcher to use Rain Chains with Canalis

This is an updated version of a previous model (https://makerworld.com/en/models/214136) - but different enough I thought it should be posted separately. The dimensions are the same and the funnels are interchangeable, but this version has decorative caps that needed a dimple/bump retaining system, and includes a number of cap designs. The new decorative caps don't seat properly on the older base design.

I'm using Monarch rain chains for this, available at Walmart and Amazon. Probably other places. But they are hoops about 2.1" in diameter and the copper itself is about 0.15" in diameter. The funnel in this model is 9 inches wide so will catch most or all the water falling from a canali depending on canali width.

The base gets attached to the underside of the canali with four stout wood screws so it should hold even ice buildups but there is a no-tool dovetail joint that allows you to just lift the funnel off the base. If there's ice coming it literally takes longer to place a ladder and climb up than to just lift the funnel off. The dovetail joint is under the canali so not much worry about ice or even water on it. It seems very secure, though, and especially with the weight of the rain chain on it. Will also be posting a tool soon to go on the end of garden rake style handles to allow placing and removing the funnels without a ladder.

The funnel is below the canali drip edge (at least on my house) so there should be no danger of flooding back onto the roof. Worst that happens is you get a waterfall not unlike what canalis give you anyway.

Some of the decorative caps for the base have a southwest motif. If you have canalis, it likely fits. There's also some happy caps with kind designs on them for those who would like subtle positive vibes and a plain cap with no design for the more traditional to hide the funnel attachment when funnels are down during winter. There's a small bump/pocket that retains them. They just pop into place and back off again. There are also a couple of utility/non-decorative caps with attachment points if you want to hang icicle lights or other decorations. Holes in those are ¼-20 thread with a 2" C-C spacing.

Like PLA, PETG HF likes to occasionally throw bits into the print when swapping colors for the decorative caps. Even though the build plates have 2-4 on a plate, I move the others out of the way and just print one at a time. The caps aren't that big and print fast. The time delay printing one cap and then the other was a little problematic with PETG HF on my system.

I originally printed in PLA but am reprinting now in PETG HF for better UV and heat resistance. The PLA ones held up great this past summer but did have some very minor sagging visible. PETG HF should add more margin. The print profile is revised but all the dimensions are the same as the previous version. The only differences are print/infill settings and adding decorative caps for when the funnels aren't up. There is a minor change to the base/mount to catch a bump on the decorative caps, though. And because of that bump on the caps, they don't fit the old base/mount that well. You can modifier them off in Bambu Studio if you want to print caps to use with the old version, but PETG or other higher temperature filament is the way. If you didn't already print in a higher temperature filament, I'd just reprint - and have. No time on them yet to know how much better the PETG HF resists temperatures.

Fill is gyroid. Gyroid adds strength but the weave is totally open. I'm hoping it will let its own internal air circulation act as a coolant with parts in shade convection cooling the parts in sun. No idea if it will work or not but sounds good and can't hurt. Anything to keep peak temperatures down for things in direct sun.
