WMSI Marker Holders

By Coltrane

For the past few weeks I’ve been working on making 3D printed pencil holders for WMSI. 

I’ve learnt a lot about 3D modeling, the design process and how to make an efficient print, all of which are vital in turning an idea in your head into a tangible object through 3D printing.


I started by brainstorming ideas and sketching them out on paper and whiteboards. Next I took the ones I liked and started modeling them in Tinkercad, a free online 3D modeling program.

Not all of them worked the first time around, but I kept going until I found two designs that worked, and that I liked.

Those designs were a pencil holder with a mouth and little cartoon eyes and a pencil holder that looked like a person sitting on the ground. 

Both designs were silly and fun, while still working well as a pencil holder.


I took those two designs and I continued working on them, making them more intricate and interesting, while also fixing any problems and errors that sprang up along the way.

And while making these designs there were many problems that sprang up!
But lucky for me, problems with a 3D model are pretty easy to catch once they’re printed.


One good way to test your 3D model is to print it, but using up all that plastic is pretty wasteful, so when I did occasionally print out a model that I was a bit worried would have an error in it, I’d print it very small.

If there were no errors on the print I’d print it at it’s normal size, but if there were I’d go back to Tinkercad and fix them.


Eventually I finished the designs. And I’m really proud of how they came out!

I learnt a lot about what to do and what not to do while 3D printing.

It was a lot of fun!
