Multitool card(updated version)

Hi , i wanted to enter the competition so here is my 3d printable version of a multitool card,i think its pretty cool,here im explaining all its features. For some time i have been thinking,What could be a versatile way of solving daily problems? So i decided to create this model.It wont take much time to print and sure it wont be a waste of material. thanks to its size you can just keep it in your wallet without any problems. Size: 6cm x 4cm with this card you can solve many problems that could annoy you It has: -bottle opener -mini saw -mini knife -can opener -5cm ruler(depending on the dimension you decide to print it) -different sized wrench(1,5 cm-1,3cm-1cm-0.7cm) -the "mini knife" can be used as a linear screw hope you like it ; ) (this account hs been ceated by my parents)-im 14 yso I made an updated version that includes: -overall thickness from 0.1cm to 0.15 for better endurance -angle degree measurement(360º) -improved linear flat screw(placed in the corner instead of being with the blade) -improved bottle oppener(thicker so that its harder and performs easier) -keychain hole -improved saw(double teeth for better execution) -improved blade(sharper and a bit longer,for easier cuts) i changed the file so that it shows the updated one. ideal printing measures: 2mm layer height 40% infill supports(activate the experimental tree supports for the teeth of the saw) 60mm/s speed
