with my current PLA printed one, weight increase is 2 g (total 143 g)
About +1.8 mm (new thickness 11.7 mm ,original by spec 9.9 mm)
Some results, see here
See post #1. It will be available with or without (It will be on inside anyway)
TBD (demo is printed with my own printer.) Still looking for best supplier. But it is kinda ok for me. not so slippery as the original toh. but looks like "selfmade" when taking a closer look.
