After downloading the original design from 'danekshea' i noticed that a sponge cut out to clean the iron was not included. So i added a small box in TinkerCAd that should fit a 60mmx60mm sponge nicely. Of course you can cut down a larger sponge or use a smaller one.
Also, after the first print attempt, i broke one of the vertical bits while pulling it off the bed. SO i added some support wedges in TinkerCAD also, this should add some more strength, and help for larger irons.
Full credit to 'danekshea' by the way for the original model, GREAT DESIGN!!!
