Rain Gutter Downpipe and Endstop fittings for B&Q Greenhouse

Over time the gutter endstop and downpipe fittings for my older B&Q aluminium greenhouse had expired with a combination of age and the effects of sunlight.   

I wasn't able to find a suitable alternative that fitted the gutters, and original fittings are no longer available, so I ended up with an ideal first project for the printer.

Ideally print in PETG or ABS, only the downpipe models need support.  They should be a reasonably tight fit into the gutters, but a little silicone sealant will help improve the seal.

Updates may follow as they are still a little work in progress, and larger downpipe versions may be added.

Jan 03 2022 - Models updated to flatten base a little more and to remove the need to part print an additional base layer.
