I loved the original design and wanted to take a stab and making my own with a latch mechanism.  Added some fun tweaks.

STL files can be broken into discrete parts for multi-color prints.  Or you can do as I did and just add color changes at selected layer positions for fun.

I printed at 0.20 mm quality with 15% infill, default settings on MK3S+/MK4S? and it came out pretty good IMHO!

Short Filament segments can be used as hinge pins as with original model.   I generally found that printing each part (upper / lower) separately produced better hinge holes rather than trying to print both parts at the same time.  I also found that I needed to sometimes clear out the hinge holes with a small hex-wrench or wire to get the 1.75mm filament to fit well.

I tried both ABS and PLA.  Generally the hinge pin holes worked well for me.  Sometimes it was a bit tight, others it was slightly loose.

I provided two sizes a ‘small’ and ‘large’.
