Summary
Nice pencil holder that was easy to design. Instructions to make one below
How I Designed This

drag 2 twisted polygons to workplane. Twisted polygon is located on page 8 (now on nine) in community shapes. They should import at a default size of 20x20mm

turn one polygon into hole and resize to 19x19mm

change height of hole to 25mm

move it up 2mm

select both then go to adjust and click align

align horizontally and vertically

group and you should have this

hold shift and drag any white dot and enlarge it to about 136x136x136mm

Project: Easily design many different pencil holders
Objective
design simple or very complex pencil holder easily by just changing the shapes and the hole
learn skills on Tinkercad
3d print awesome creations you make yourself
Audiences
anyone who is new to Tinkercad or fairly new
preparation
you can use any computer
little experience is required
and you will need a good internet connection
Step one
sketch the pencil holder you would like to design
step two
design pencil holder similar to how I designed mine. You can experiment with it by shrinking hole more or less then I did. Change the shape to any other shape most work. It is also possible to adjust twist of polygon.
results
You should have a 3d-printable pencil holder when your done depending on the shape and size of the pencil holder

I used twisted polygon 4 instead for this one

same thing but with hexagonal prism

shunk hole to 18x18x18mm
