R2-D2 Wheel Sprocket Adapter for Mr Baddeley's v2 design
Description
CAUTION: Still in beta testing. These parts allow for using a VEX PRO 2637 (#25 Plate Sprocket - 40t) with MrBaddeley's R2-D2 v2 design (https://www.thingiverse.com/mrbaddeley/about). They are meant to replace the following parts of the original design: Beltv4.stl, LCentrespindle.stl, LDriveWheel.stl, LMotorDriveWheel.stl Here's the order in which I installed the parts: 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 a threaded rod of 8mm, with one nut or each side and 2x washers separating the nuts from the rest of the wheel. However, there are some issues that I haven't yet been able to resolve: 1. The tire scratches the top of the frame, when I put some weight on the foot, 2. The wheel has a lot of play, which is partly caused on the opposite side of the belt/sprocket. Not good for the bearings. Resolving this may likely resolve the first issue, too. Hence, this is work in progress and I can't recommend using this setup as yet, until it's 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.
