REMIXED - Latch with Locking Mechanism

I love the model Adamix created! As soon as I saw it, I knew exactly what I was going to use it for: My cat's litterbox enclosure.

So this was one of the first practical prints I ever printed on my 3D printer. But I was having issues with the sliding latch and locking screw. And that's how I came up with this.

I actually ended up remodelling the whole latch piece and knob in FreeCAD. I made the piece slightly longer and a little bit thicker to fit snugly (but freely) in the housing. Then, I recreated the knob to be wider and a bit shorter for ergonomics. And I also added a “lip” to make contact with the face of the latch housing to lock it down. And so far, it has worked FLAWLESSLY!

I printed both parts in the same print, with the following settings on my Ender 3 V2:

• .2mm layer height
• 75% Infill (or more)
• Triangle infill pattern
• 3 or more walls for rigidity
• No supports
• No Brim/Raft

Making this remix was a lot of fun, and like I said it turned out great! This was printed in SUNLU Black PLA+ from Amazon. It's held up so far for the last month and has worked great for my application.

Big thanks to Adamix for sharing the original! I hope others will find this remix useful.
