Pencil Tip Protector/Cover (1g)

My first design ever! Please go easy on me. :-) I love writing with Pencils and wanted to learn and design something useful. Here is my first design attempt ever. 1g only. This fits snug on most of the pencil models I have. Like studymate, blackwing pencils, staedtler, apsara, faber-castell and generic pencils. Dimensions:Bottom pencil diameter, 7.3 mmTop pencil diameter, 5.0 mm (tapered design)Total height 40mm (or 4 cm)Wall thickness, 0.9 mmHappy to receive any feedback and/or tips. Thank you. Note: You might want to add extra layer on top if you want smooth finish.
