Lewihe Play base for TR8x8 leadscrew and nut

thingiverse

I saw the design that the guys at Lewihe published here for using in the base a miniature nut spindle and I loved it, thank you guys!. Anyway I had lying around some TR8x8 leadscrews and nuts and that made me think why not? As I couldn't find any design of the base I made my own version. You will need 4x M3x16 screws, 4x M3 nuts, a TR8x8 nut and leadscrew, and a transmission adapter 5 to 8mm. It is a cool update for me because I hate that ugly and noisy M5 rods. Believe me when I say that once made this change the printer will never look like a toy anymore... I post here my FreeCAD sources just in case you need some adjustment to your setup. Remember that you have to modify your marlin settings to have 400 step/mm for the Z axis as the TR8x8 rods run 8mm each turn. This design is similar to the nice one the Lewihe's guys published here, but my design is simple and coarse like me. Note: When I was looking for the TR8x8 nut specs I found that the holes were M4 so I designed this thing accordingly. Unfortunately when my nuts arrived only M3 bolts fitted in the holes and I had to figure out a way to use them (easy). I redesigned the part to fit M3 screws and updated the .STL also. (UPDATE 24-MAY-2016): A small fillet was added to make it easier to use the lower bolts for adjusting the height of the bed.
