a few moths ago i ordered an smok skyhook from china. the first 2 weeks this device worked perfect. but after the 2 weeks the thank began to leak and was unfixable. so i have designed a hole new cover for the parts from a skyhook rdta box. the bolt i use for the thank insertion is a bolt with inner diameter of 51 mm. the negative can be soldered on to the bolt and the positive directly under the bolt. this is not yet on the screenshot but it is in the design. pictures of actual build will follow skyhookvapebox.stl isa new version instead of a bolt u used the 510 connector from a ohm reader
