Remix of RobFlip's V1 Tevo Tarantula Bed Support Main Body - wheel slop removal - acrylic part elimination

thingiverse

This is a remix of RobFlip's V1 bed support for the Tevo Tarantula. https://www.thingiverse.com/thing:2572598 <-- Original File This version uses the stock wheels but has precision holes for the stock wheel bolts and eccentric spacers as part of this model. The RobFlip original retains the stock acrylic smaller H-shaped piece that goes below the large bed support X-shaped piece - this eliminates the need for that. The holes for the wheel bolts and the eccentric spacers are 41.5mm apart (laterally - along the X axis if you will). This is .5-1mm closer together than the sloppy stock acrylic pieces that come with some Tarantula kits. Stock longitudinal (along the Y axis) bolt spacing is retained. The holes may be a bit undersized depending on your particular printer - they may need to be reamed out slightly with an x-acto knife, file, or drill bit for a good fit, but I felt this was a better solution than designing larger holes that may print sloppy on some printer - since the whole point of this is to eliminate slop in the stock system. This original file is deprecated now as there is a V2.0 bed support that is shorter (retaining more Z axis travel) and has other improvements. But I have it finished and printer and extensively tested so I thought I'd upload it. I can also upload a version of the V2 bed support center section with the same modification set, but I don't think I'll be printing V2 for some time, so it would be untested if I did upload it. Still, I will upload it if anybody asks and is willing to be the guinea pig tester. 5/1/2018 EDIT: I uploaded a second version of this - denoted with BELTALIGNED in the name. When using this part to eliminate the smaller, H-shaped acrylic part that came with the printer, this lowers the point where the Y belt attaches to the Y carriage by the thickness of the acrylic part by about 5mm. So, the part denoted BELT ALIGNED has the belt attachment point raised, gussets added to reinforce the raised belt attachment point. This part *might* need small supports under the raised attachment point as it no longer sits flat against the bed. It *should* print as a short (10mm long) bridge, but that might depend on the slicer you use to print it. I have not actually tested this part yet, but I don't foresee any problems with it, but print at your own risk (of wasted time and filament). I have encountered no problems with the original file in operation for more than a month on my personal printer. It may cause a slight dimensional inaccuracy on prints that reach close to the edges of Y travel. But I have never encountered this in practice. That said, my perfectionism prompted me to make this slight alteration of the part.
