The various colors show that I printed it little by little as time (and different filaments) went by.
I wanted it as a low-cost low-speed toy for inside the house for my 7-year old son. So, I printed bushings instead of bearings, a no-steering link for the rear and a gearbox for standard size servo (which I had). These are in the remixes. Also, I happened upon a bigger bicycle tire tube and had to change the suspensions a bit to accomodate this. Then I put crawler tires on it.
Problem is, I used the first version of gears and they just don't do - it doesn't move. But before I install the new version of the gears, I want to design the rest of the upgrades I want to make:
- more steering angle. A conversion to RWD will help with this, so
- different central gearbox
- convert front gearbox to just a rigid link
- different spindles:
- thicker where the screws connect them to the steering link (they tend to break there)
- convert them to use wheel axles instead of screws (search "rc wheel axle" on aliexpress or ebay)
- different design for the front ones for more steering angle and no axles
- reduction gears for lower speed, probably in the center gearbox or between it and the motor
- on the suspensions, thicker holders for the gearboxes - they also seem easy to brake. Also make them use M3 instead of M2 screws for the connection of the two suspension parts
- an actual truck bed for carrying things (kids love carrying stuff with their toys!) and a tow bar.
But frankly, this is a lot of work to do without the source 3d files, so I'll probably won't do it - just go along with another design.
Now, if the creator designs these options, it would really be very nice of him :)
