Thanks to StormtrooperAimm for the original files. This remix is primarily to improve printability.
I did this by increasing the surface area of parts in contact with the bed to reduce risk of them getting knocked over. I also integrated the pen tip with the body so you don't have to glue that.
I reduced the size of the nut so its a tighter fit but you still have to glue or heatshrink it on to prevent the twister from coming off.
Uses a common Bic Pen available literally anywhere. https://amzn.to/2SMRtQk
Print solid, a brim is recommended. Have fun!
