Davinci 1 left Y axis carriage for 15mm x 8mm linear bearings

pinshape

Finally a hassle-free printing solution for the left Y axis carriage of the Davinci 1 that's as accurate as it is easy to print. This design enables the use of larger and more precise 15mm OD x 8mm ID linear ball bearings, further enhancing overall accuracy. The two-piece model naturally relieves any misalignment stresses between X and Y axis components when bolted together in their natural state. To assemble, attach the bottom half to the X axis rods and the top half to the Y axis rod, then secure them with bolts. Next, attach the X and Y axis belts after assembling the Y axis carriage halves securely. Required parts include 4ea) 3mm x 16mm screws, 4ea) 3mm nuts, 2ea) high-quality 15mm x 8mm linear bearings, and 1ea) an 8mm hardened rod, machined to fit the Da Vinci1 chassis. This design incorporates the original belt tensioning mechanism for seamless integration. A crucial note: you must add your own flag for the end stop switch as it's not included in the model. To ensure optimal performance, linear bearing bores should be precisely 15.2mm and rod holes exactly 8.5mm to account for any model shrinkage during printing. Both bore types should be reamed to size for maximum accuracy. If your 3D printer is particularly accurate or produces flawless holes, you may need to adjust the bearing and rod bores on the STL file accordingly.
