So I have a breaker from Aldi however the handle used to tighten the grip was too large to fit into the case when attached. So I made a version that was shorter but still nice and chunky to give a good grip.

Because of the lower rounding you may need active cooling.

Because the hole is printed upside down I tend to close it completely which allows the bridge to work nicely and then simply drill out the bridged area afterwards.
