Small dustpan V2

Summary

Work in progress because my 3D printer is down and I am not able to print it to check but I'm fairly confident that it will be fine.

My previous design was too thin and caused the edges to crack and break apart.

I have thickened the walls and made it slightly shorter while maintaining the overall width of 150mm. All these changes will improve structure rigidity.

I have printed in yellow ABS and observed some warpage at the thin wall areas holding the stick. Not a big issue to me, don't expect to see this if printed using PLA.
