Our household has 2 cats (no, they're not mine: I just have to put up with them).
One of the cats is a particularly prodigious drinker (of water: get your mind out of the gutter
). My wife bought a water fountain for him (the cat), but it was a type that cascaded the water over a 360 degree lip, one shaped a bit like a mushroom head. The cat didn't like it and wouldn't drink from it.
I removed the original fountain top and replaced it with a piece of copper pipe. That worked OK, and the cat drank from it, but the water made a lot of noise coming out of it and the pipe plugged up too often.
I found a spigot on thingiverse.com: https://www.thingiverse.com/thing:3383575. I printed it but, of course, the diameter was not correct for the water pump that came with the fountain. I used F360 to create an adapter. It worked really well. The only issue was that the end of the spigot was a little too low for the cat to use easily.
To correct this issue I extended the length of the adapter I designed in F360 and printed it. I installed it on the fountain but it broke at the layer where it meets the water pump. I figure the extra length contributed to allowing me to over torque the adapter, so I decided to add a cross to the inside of the adapter, to reinforce the layers and add extra strength to the whole thing.
I tried modifying the existing F360 design, but that proved more difficult than I had figured. I started from scratch, doing things in a way I've never done before.
While the new design was printing I took the opportunity to attempt to design the adapter in FCAD. I actually succeeded. Here are some captures of the design:
This is the sketch for the cross brace. It was done on the XZ plane. I took care to set the padding as symmetrical, so the 2 planes of the brace would cross at the center.
This is the previous sketch padded to 1.2mm.
For the very 1st time, I use the Polar Pattern command. I set it to 2 copies at 90 degrees. Because I made sure to Pad the sketch symmetrically, the bodies cross each exactly at the center.
This is the sketch, again on the XZ plane, for the outer wall. The lines are 1.2mm apart. I used the previous sketch as a guide for placing these lines.
No, it's not a bullet casing 😋 This is the previous outer wall sketch Revolved 360 degrees; the 1st time I've used that command.
