Vỏ bọc bật lửa (Lighter case) - Thiết kế chống trượt

I desingt a lighter case. At the moment I have two designs one with straight ribs down and one with ribs which is wavy. These lighter holders are very good to get more grip on a lighter. Due to the waves on one model you don't get any more rattling and both are also better in the hand. I have designed a hole on the underside so that you can change the case more easily.

Print Setting:
I printed it with the standard printer settings (Bambu Lab P1S)

Update: I have updated the wavy ribs version. The shafts are now better adjusted and it now sits even better in the hand. And the ribs now go through.
