for my Lack composition I created this attachment for the legs of the upside down tables to house my prusa and in one I made 4 holes 7.5 mm to bring cables to the upper module
The hole to fix the object to the legs of the LACK is 3mm conical with a 7.9mm head
It is possible to print it straight or lying down without supports
NOTE
In my profile other components to create a 4 LACK structure
Printer Prusa MK3s
0.20
no support
