updated Frog Box

I updated this Frog Box ( https://www.thingiverse.com/thing:4094861 ) in order for the parts to fit and better print on my **Prusa i3 MK3S+** The top shown in the picture has some logos printed, but the top file here is blank.
Here are the changes:

1. Now the 20mm screws actually fit to the end of the latch bracket. Before they barely touched the other side.
2. The spring hinges are now set up to just work and attach properly. Make sure the cam part of the hinge is on the bottom case and it will now work. Before, they would end up cracking the hinge bracket because they didn't fit correctly.
3. Added a little thumb lever to the front latch to make it easy to unlatch.
4. Some topology clean-up.

These were all created from the original STL files and I used Blender and KIT OPS to update.

These parts were tested on PLA and PETG, and both on the textured and smooth print plates using both PRUSAMENT and OVERTURE filament (both PLA and PETG). Please be sure and use PETG on the
