Polargraph Gondola see-through

thingiverse

I have taken the design for Polargraph gondola and have remixed and re-created it so it's possible to see through it to see the pen and it drawing. You will need to print: 1 x gondola 2 x hubring (NOTE: I had to print the hubring at 103% scale or else it would be too tight) 2 x hubspacer (optional) 1 x hubcap (optional, I just used a zip tie) The fastening mechanism uses an M4 screw and a threaded insert, you have to heat and melt it into the plastic.
