i was updating my prusa i3 and decided to get printed z couplers and a fan mount. The z coupler is not as flexible as i hoped but still does the job well
. I was using tubing and zipties before.
I added the brim function on the fan mount to avoid corner lifting. Both are printed using PLA, at 0.2mm layer height. I got my Prusa i3 as a kit from www.3dprinterczar.com.
Let me know what you guys think
