I have made a prototype of the attached drawings but the gears didn't have enough torque and the wheels slipped on wet floors.

I made the following changes to the prototype I built:
1. I duplicated the front Wheels (Part #23) to replace the back wheels (Part #3)
2. I duplicated the Roller GearWheel V2 (Part#9) to make the back wheels work the same as the front wheels
3. I duplicated the Reducing Gear (Part #24) to connect the new back wheels to the gear mechanisms

The gear torque works great now but the 4 wheels still don't have enough surface contact to stop slipping on the wet floor. I believe all 4 wheels need to be wider to have more surface contact to stop them from slipping (hydroplaning).

I need the wheels to (#23) to be as wide as possible and change as LITTLE as possible to the rest of the parts and avoid extra costs.

I am pretty sure I will need to re-print the Reducing Gear (#24) to make the wider wheels work with them.

If I have to adjust the holes on the Plate (#7), I would like to do it with a drill instead of reprinting them.

I am hoping there will not be any changes needed to Roller GearWheel V2 (#9)
The winner will have the most elegant solution at the lowest cost that will solve the problem of enough torque and no slipping.

I agree for a "fancy solution", but what I really need is just the cad files edited, no solution necessary. I just thought if I explained the problem and someone has a better way to do it other than editing the 2 or 3 files (which is a simple modification) then I will consider those ideas more heavily. But, it is not necessary, as long as I get the couple files I need slightly modified as explained in the challenge. I hope that makes sense???

The prize is not very fancy for a fancy solution, do you agree?: V

The rollers are sponges that spin and mop the floor.

what is the use of the machine to better help understand the modification required and have you calculated the gear ratio of your design ?

3D CAD Revision Of Skull & Snake
I need a simple revision of this design. It was created in SolidWorks but I guess it can be revised in any 3D CAD software as long as the file is saved .STEP. A mold will be made from this in a CNC Milling Machine but as it is now can't be made because there is a space between the snakes body and the top of the skull. The body of the snake has to move down. See attachment 2 for exact position. You can download the original STEP file to work on. It is the first attachment but might take a few minutes as it is a large file.
Stackable dresser
I have provided a basic design of a piece of furniture that I would like to provide to a CNC fabricator to be cut out for assembly. I need my Powerpoint sketches turned into a 3D design and the component pieces layed out for cutting on the two pieces of plywood to be used. This design will be sent to the CNC fabricator for cutting.
