Card Holder
this is a cardholder that will hold your cards for you and spin to get to your cards easier.
Supplies
for this, all you need is a 3D printer, filament, slicing software, and cards to use for measurement. I recommend (petg because it is a strong filament)
Step 1: you want to create a cylinder big enough to fit cards, then you want to create a triangle to securely hold the cards in the slot then you want to change the triangle into a hole to make a hole in the circle for the business cards.
Step 2: you want to create a hole to the bottom of the circle so you can hook the cylinder to the base, you also want to put a circle there to make it rotate easier.
Step 3: you want to create the base by using either circles or rectangles and combine them together to make a stable base that is big enough to hold the cylinder, you also need to make sure to put it apart to hold the cylinder
Step 4: Lastly you want to put 2 rectangles 1 for each side so when you put it together you have a way for the cylinder to not fall off, but you want to size it according to the holes you put in the side so that you can attach it but it won't interfere.
