Hello!
Before we start I'd like to tell you a little about myself, I'm a 16 years old student from Israel playing for the local robotics FRC team as the head CAD department. I mostly design random contraptions of things that sound impossible and slowly make them work; for this project I have a literal shame-can with about 50 broken, too tight, too large, too stiff, too small, cut inducing or generally failed prototypes but I wanted to get it just right and did not have a lot of time to do so.
And oh boy, am I exited for this one!
I made these designs originally for the MakerEd Challenge 2.0 with about 80% of the work done in the AM's.
The idea for this project is from every day observations in my school. I see my Math teacher struggling to draw a shape that is even close to a circle for Geometry lessons. I see my Robotics teacher barely able to dash over sketches on the board without leaning the whole arm (with a simple modification the same Dasher and do many types of lines, but Math teachers barely need center-lines or Mirror-lines). And I can see my fellow students (including myself) unable to copy Geometry assignments from our book to our notebook, and also my teachers planning the next homework task or test, they also need to copy those markings! We all have enough to worry about with the assignment itself and we don't need any more obstacles. The gadgets I made work with Sharpies and Expo What-Board markers for a few reason, they are sold all around the world and have a very consistent structure.
But to be honest even as a student with a white-board in his room, I could still use those gadgets with home work, planning my next project and drawing!
Printer brand : Printrbot
Printer : Simple Black
Rafts : No
Supports : No
Infill : about 15 to 25 should be good.
Notes : I am using Inventor 2016 that has a known problem with scaling down objects 1/10 (cm/mm) so just scale everything x10. Also in the Pentagraph you need to scale the joins down 0.001. I for the life of me have no clue why and tried re-sketching them multiple times, still the same problem. ¯\_(ツ)_/¯ As a fellow 3D printer enthusiast, I strongly dislike printing with supports, and so I took the hard way out and am glad to announce that all of this project is support-free! Thank me later :)
Post printing
General notes.
A simple nail-file or something a little more clever or industrial to get rid of any excess material is needed. There are no supports as I have stated earlier but a lot of the parts I made here on this project includes are very small, and so, my printer tends to not be really accurate, I've tormented that poor thing over the years.. Your printer might not have such problems but it would still be handy to keep one around. Also, for the Dasher 2 rubber bands are needed or alternatively, you could use some good ol' Silicone Caulking to create the resistance with the board. In my room I used a Glass board so a lot of resistance was needed.
