Clippless magnetic body mounting system for 1/10 RC. No more holes and sticking poles from the body.
You will need:
-Magnets
-14 M3 screws
-washers (optional, for adjusting the mount width)
Added a washer STL to save you a trip to the hardware store.

I suggest you to print the posts vertically (on a raft to overcome elephant foot), so they are nice and round (If you crash too much and end up breaking them you can print them horizontally for more strength).
Print everything solid for best results.
The mounts will need support,mainly on the horizontal cut - you can add supports there manually or enable supports and block them for the rest of the part/parts. After printing use knife to remove the support material.

Enoy!
