Slim Pencil Box

Designed this thing after I saw a YouTube video on a laser cut box for a calligraphy pen. In this case I wanted something to hold a few pencils for school/work. The lid slides in and out to close up the box. The slots the lid slides in are tapered so the lid does not come out. Lid should stick out a little due to the tapered slots. The box should hold up to 5 unsharpen pencils.

Overall dimensions are as follows:
Length = 200mm
Width = 26mm
Height = 27mm

Please let me know if there are any improvements I could make. Enjoy
