Rv Screen Door latch

My RV screen door slider never was long enough to catch on the door frame and stay closed. Then the tab on the inside cover broke. So I created each of these parts for the Challenger Door 950-SCR latch.
There are 3 total parts in the original setup but only the slider and top cover needed replacing.

NEW UPDATE 5 July 2025
After a nice person messaged if I might have a different knob design I decided to to revamp my original design. I also had had some problem with screws not quite fitting holes and the handle thing keep braking off. The knob idea had been percolating and with the recent message for one, here it is. All new files are labeled with "v2" and added some pictures too. Note the original knob/catch thing still has to be on the front door side so it can catch on the on original door piece.
Hope this helps those of you with the same inadequate latch on your RV.

Please Note:
Be sure to adjust your screen door catch (plastic part with 2 screws on your door) so it holds the scr
