For this model you will need 1 M2.5 Skadis T Nut. It should work also with M2 screw, if you need it for M3 feel free to ask for a remix

There are 2 version, open and closed, print the one you prefer.The alignment guides are designed to be printed without supports.

Note that the head of the screw must be smaller than 4.5 x 2.5 mm otherwise it will impossible to insert the lighter.

If you have any question/issue/request just leave a comment ad I will be happy to help.
