Walking on wild side…
no more teaQR you know you are creazy to use all ob as structure? next update are convert it in mixqr and make other 2 of this!!
Ratrig had a deal: I bought the whole kit for 65 euros (12 x 500 mm OB + Screws + Corners). Plus, it easier to attach the leadscrews, so I would have saved only 4 beams. Bahhh! Doesn’t worth the trouble… More tea is coming.
I’m quite happy from the performance of the printed drum. They seems pretty much effective and precise.
