Foldable Hook to mount to your wall which will give you 2 modes:

• A short hook flat to the wall for a single piece of clothing
• or if you slide the hook up and forward it will provide a longer “rail” hook to put more e.g. clothes to.

Here are some pictures of a draft print:
 

Printing instructions:

• Raise to ≥5 the wall perimeters for more strength
• Infill ≥ 40% could help to to raise the strength 
• Print the „hook“ part laying flat on the bed to add strength
• Small amount of supports needed from the print bed (base upside down printed)
• Using a brim could help if you face problems with adhesion
• 0.2 speed profile
• Textured sheet recommend:
  • If you use a textured sheet too, let it cool down completely after the print and wait for the part gets loose by itself. Do not pull on it to avoid ripping off the letters! 
  • In my case it takes 45-90 minutes after the print has ended and the part just lays loose on the print bed.
  • Do not touch the print bed and clean it with Isopropanol alcohol before printing.

Parts needed:

• 1x M3x8 screw
• 2x M4x15 screw
• 2x screw with max. Ø6mm to attach the hook to your wall

Happy printing =)
