R2-D2 Wheel Sprocket Adapter for Mr Baddeley's v2 design

thingiverse

CAUTION: Still in Beta Testing. These components enable the use of a VEX PRO 2637 (#25 Plate Sprocket - 40t) with MrBaddeley's R2-D2 v2 design (https://www.thingiverse.com/mrbaddeley/about). They replace the following parts from the original design: Beltv4.stl, LCentrespindle.stl, LDriveWheel.stl, LMotorDriveWheel.stl Here is the order in which I installed these components: M8 Nut => 2x M8 washers => Wheel => Bearings => Updated Spindle (included in the STL) => Bearings => Sprocket's Adapter (included in the STL) => Sprocket => Sprocket's Cover (included in the STL) => 2x M8 washers => M8 Nut. Tested with: M8 washer thickness: 1.4mm. M8 nut thickness: 6.5mm Bearings inner diam.: 8mm, outer diam.: 22mm and width: 7mm Chain 25H for 47/49CCT Mini Moto Pocket Bike Atv Quad Scooter (29 inner pieces + 1 chain link). For the wheel, I used an 8mm threaded rod with one nut on each side and 2x washers separating the nuts from the rest of the wheel. However, there are some issues that have not yet been resolved: 1. The tire scratches the top of the frame when weight is applied to the foot. 2. The wheel has a lot of play, partly caused by the opposite side of the belt/sprocket. This may resolve both issues. This setup is work in progress and cannot be recommended until it is fully tested and any pending issues are resolved. Versions: version 0.4 beta: first iteration. version 0.5 beta: increased thickness of adapter by 0.15mm.
