Elcan killflash kit

Print it, and clip on your Elcan scope & RMR red dot. It is a tight fit for the scope, so maybe you'll have to trim the edges a little bit. To put the red dot firmly in place, you'll need to bend slightly the sides while heating the pla (i use a standard hair dryer) I bend it in order to have 1cm space between the two sides.
