Scalpel cover

Did this simple scalpel cover to keep the very sharp blade covered. It fits this one (not the round blade): https://www.aliexpress.com/item/4001294172638.html?spm=a2g0o.productlist.0.0.7c067dd4QRwZ8H&algo_pvid=2c8e8a8f-ac2f-48ec-ab33-d9f32ac3deee&algo_expid=2c8e8a8f-ac2f-48ec-ab33-d9f32ac3deee-5&btsid=0b0a556616058539049613093ec15f&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Print it upwards. I recommend using a raft so it can handle minor hits from the printhead.
