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

Finally an easy to print and accurate left Y axis carriage solution for the Davinci 1. This allows for the use of 15mm OD x 8mm ID linear ball bearings for better accuracy. The model is two piece which when bolted together in the natural state can relieve any misalignment stresses between the X and Y axis components. Attach the bottom half to the X axis rods and the top half to the Y axis rod and then bolt the two carriage halves together. Attach the X and Y axis belts after securely assembling the Y axis carriage halves.

Required parts are, 

4ea) 3mm x 16mm screws. 

4ea) 3mm nuts, 

2ea) quality 15mm x 8mm linear bearings, 

1ea) 8mm hardened rod, machined to fit the Da Vinci1 chassis.

Uses the original belt tensioning mechanism.

IMPORTANT!! 

You need to add your own flag for the end stop switch. The model has no flag for this.

Linear bearing bores are 15.2mm to allow for model shrinkage

Rod holes are 8.5mm to allow for model shrinkage

Both linear bearing bores and rod bores should be reamed to size for model accuracy.

If your 3D printer is very accurate, or makes perfect holes, you may need to resize the bearing and rod bores on the model stl file to suit your needs.
