ACE Pro external spool lid opener

This quick print allows you to keep the lid of the ACE pro open which makes it easier to print with an external spool holder if your filament is too large for inside the ACE. Note: Automatic rewinding will not work if you use an external spool holder. Print Settings: .3mm layer height supports enabled How to use: Align it with the small bump on the ACE pro lid to keep it from collapsing.
