Recommended Upgrades and Spares

All,

I am expecting the delivery of my TAZ 4 today and am interested to hear your opinion on upgrades that should be done sooner rather than later and spare parts that I should order and/or print.

I have little experience with 3D printing and thus far ABS is my material of choice, but I intend to try a little of everything. :smiley:

Thanks!

Robert
