Window curtain holder hooks

This is a simple hook I made for holding the sheer window curtains open in my dining room.

My dogs have a tendency of getting overly excited when they see animals in the pasture behind my house.  I've replaced the mini-blinds twice since we moved here three years ago, so we've been leaving them half way up.  I recently installed curtains and just wanted a quick easy method for holding them open and this is what I decided on.

I print two of these, one for each side of the windows.  I expected to print these as modeled in the STL without supports, raft, or brim, which should have been a quick easy print but the flat edge with the screwholes separated from the PEI sheet of my Ender 3 twice so I ended up using a brim.

I would have tried printing these on another machine but since the Ender 3 had white filament.  I decided it would be quicker removing the brim from my prints than moving the white spool to another machine.  If you have good bed adhesion, you shouldn't need a brim for these, but I did, so I'm documenting my failures here in hopes that it may help others who have trouble printing this.
