Tarantula Rear Tower Support

thingiverse

The main challenge with the Tevo Tarantula series is its reliance on a single frame design similar to that of the Prusa i3 variant, which often results in a swaying motion towards the rear due to uneven weight distribution.\nTarantula's weight tends to accumulate at the back, causing a noticeable high skew angle of 1.423 degrees off a standard 20 x 20 x 100mm cube.\nThe addition here is meant to support the frame tower by pushing forward, aiming for as close to a 90-degree angle as possible on the z-axis (between y min and y max).\nFor users employing the stock acrylic motor mount but still desiring rear tower support, I created this part to also support the acrylic with the rear support.\nPost-Printing\nPrinted t-slot nut\nYou may need to file down the t-slot nut holder for smooth insertion into the slot without issues.\nTop Long.stl\nYou might have to file parts by at least 1mm thickness due to the supplied stock acrylic being approximately 21mm instead of the standard 20mm following aluminum profile.\nCustom Section\nBill of Materials (BOM)\n2 x 50cm, 8mm diameter threaded rods\n2 x at least 20cm, 8mm diameter threaded rods\n14 x nuts compatible with your threaded rods\nAt least 8 spring washers, 4 on each side\nAt least 5 m4 x 10 screws\nAt least 5 t-slot nut; printable ones can be found here: http://www.thingiverse.com/thing:1289978\nPrint each part requiring one of them separately for each side.\nRecommended to have a long spirit level or a long metal ruler on hand.\nMounting the Brackets\nWhen mounting the bracket, ensure that the diagonal 50cm threaded rod can slide freely between top and bottom brackets for optimal clearance. After identifying the clearance as smooth, tighten the nut holding the bottom bracket on the horizontal bar while checking the diagonal rod's clearances.\nOnce the bottom bracket is secured to the horizontal bar, screw in the threaded rod to lock it into place, followed by tightening the nut atop the bottom bracket securing down the diagonal.\nTop Section\nTighten both angles simultaneously - top and bottom parts of the tower - while checking the tower angle. Adjust for your preferred level of accuracy.
