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 ?

4 simple CAD 3D print ready items required (drawing supplied) - ongoing work
We have 4 items that we can knock up in sketch up in about an hour. However, sketch up doesn't handle recesses or chamfer very well. We are looking for these 4 items (2 are incredibly simple) to be made print ready for us to print, test and revise.
