If you have access to a 3d printer you can get this little helper for nicer stamping. The file and the kit itself is available on @CryptoCloaks

 Thanks ! 

 wtf is this 

 The plastic thing? Just a tool for better stamping and spacing of the letters. Pretty smart actually 

 I’ve got the older version and it’s great. Takes some time to do but much cheaper than fancy metal plates.
