Gridfinity Folding Ruler Cup h6/4/3

I was looking for a space saving gridfinity cup for a 2 meter folding ruler but couldn't find one ;-)

Base is a half pitch x 6h, no magnet or screw holes, thanks to Max@Ostat for the pattern! 

Size of the Ruler should be around 24.3x16.3x33.7mm

Models available: 

• 0.5x6h  (hight: 45.75mm)
• 0.5x4h  (hight: 31.75mm)
• 0.5x3h  (hight: 24.75mm)

Let me know if other sizes are desired.

Thanks for your likes ;-)
