About this 3D model

EDIT 13012018: Good morning, here is the ring mounted final version (green). Just to say that I've drilled the diameter of the holes to 5.5. Indeed, the diameters produced at printing are too accurate. And the tray turns perfectly "round" ! ;) EDIT 10012018: Good morning, here I am again to make some small changes to the file. In this version I integrated the 4mm wooden washer that I had made and placed at the back of the nut in order to prevent it from dislodging from the ring while turning. The ring is perfectly cylindrical this time, and I also directly provided the housings for the M4 nuts. I think it's all there this time, sorry for your impressions already made, but it's proto! Enjoy! LTDO P.S: concerning the direct threading project in the printed part (to replace the M33 nut), we forget. Metal versus plastic does not work. Good morning, I propose you here a ring proto for nut M33 x 3,5 for wood lathe. It is a ring in which a nut is inserted for the design of a recovery plate, in order to finalize pieces of wood at the end. I still have to design the same ring but this time with direct threading in the part. Two threads will be proposed: M33 x 3.5 (European) and 1' x 8TPI (us/uk) See you soon. LTDO P.S: see Youtube wood lathe cover tray. https://youtu.be/ixh1VTAenEk
