I found it didn't put quite enough pressure on the panel and my attempts to modify the cad failed
Decided the best way to understand it was to design it
Wanted adjustable "pressure" and thought using a sweep on the latch was a nice solution making the most of the flex of ABS
Wanted everything as a parameter so I could tune it
Build plate density, a bonus of using a filament hinge is that the area used for each hinge is much smaller
45 instances on a 250 buildplate
Hardware
3.0mm-5.5mm - m3x12
6.0mm-8.0mm - m3x16
8.5mm - m2x20
The process
Cad attempt one failed, just modified surfaces to create a filament variant but adjustment beyond that failed
Cad attempt two failed, created a traced version copying the dimensions but again couldn't get a reliable adjustment
Cad attempt three of the cad sketch made as built was finally onto something, took until v45 before I had something that seemed to fulfil my requirements, then after thinking overnight revisited earlier designs and finally hit RC at v68 (18 actually printed)
Final design and thankfully discovered sheeter (now defunct sadly) which allows me to produce many stls based on parameters
