Not really a problem, the only possible complication would be finding compatible screws, although that's probably easy to fix. I use M4 bolts, but a 3,5 wood screw with flat head in stainless steel would work just as well.
I do have a set of new blades with the proper Lenz2 dimensions which I still have not gotten round to upload yet. I attempted a gear drive using a printed MOD1 spur, with a 34t MOD1 pinion (5mm bore, traxxas). But that makes way too much of a gear whine at any wind speed.
I've gotten some T5 belts, but have you to print the pulleys for it to try that, it should make it alot more quiet.
Could use some help as my Mendel90 just broke the extruder motor mount.
