Straight Forward 2D to Symmetric 3DBlind

I need a 3D CAD Drawing of a Dagger in a high-res STEP Format. It will be used for 3D Printing and also a graphite mold will be produced on a CNC Milling Machine. The mold will be used for casting silver. Attachment 1: Please follow this sample in regard to detail on the handle and the curves on the blade. Keep the length of the blade on the short side. This is a dagger......not a sword..

We're in the process of producing a size range of cylindrical indoor/outdoor planters and need a high-res STEP file to provide to potential manufacturers. This is a high-end homeware product so small details are important. We are open to any small design elements within the specified parameters that keep the product clean and minimal.

We would like to create a boardroom pop-up, it will look like a Jelly Fish. It will have a 4x2" Multi Media Wallplate at the stem(Oral Arms) and the Bell will be hollowed out to hold all our cables, and on the outside of the bell, we want to install plug sockets.

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). Challenge: 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)
