I often find myself disappointed by the selection of wheels available for touring and drift cars. Things are better than they were, but one of the best brands for choice and availability was HPI, but unfortunately the brand seems to be in continual trouble and AFAIK its future is still in question. There are now some great new manufacturers on the market but it can be a lottery getting the right wheel at the right time and the right price. What could be better than wheels on demand? It was @CarterTG's thread on wheel printing that encouraged me to buy the Elegoo Mars in the first place. If he can get a successful wheel print, then so can I, right? This thread will document my progress from prototype to finish or failure, and point out any issues along the way so anyone working along with their own resin printer will be able to learn from what I've done. So, with my future as a wheel designer laid out before me, where do I begin? First - with an idea. Ultimately I want to have a range of wheels in a range of offsets, so I began by designing a rim and hub based off a standard Tamiya wheel. 26mm wide, with inner and outer beads and a 1mm wall thickness. The hub is oversized but that allows me to subtract from it later to make unique face patterns on later designs. Offset is a standard-ish +3mm, that is the back of the hex is 3mm towards the outside of the rim from the centre. This seems to be about right for a Tamiya wheel. Actually the measurements I took from a standard wheel weren't absolutely the same, but the wheel was used and my caliper is cheap so I wasn't expecting 100% accuracy. More to follow after I grab a coffee...
OK, this has been a bit of a labour of love for a few weeks now. Still in the prototype stage as I type, but I have a spare evening so I figure it's time for some admin and an update on progress. So, wossis then? Well, it's a winch mount / tough bumper for the Axial SCX10 G6 Rubicon that has been my go-to rig for trail duties for a few years now. For why? Various reasons. 1) The stock bumper isn't perfectly flat, so it's not easy to mount the winch on it. The 3-Racing winch has a big metal base plate with built-in fairlead, and it doesn't sit right on the G6 bumper. 2) The stock bumper (and mount) are flexible ABS. Good for avoiding breakages on the trails, bad for winch duties. In fact with the ground anchor hooked over the roll cage for stowage, the entire bumper twists and looks ugly. 3) I have Proline Flat Iron XL tyres with a huge 120mm diameter, which catches on the corners of the stock bumper. So, to begin with, I found this thing: https://www.thingiverse.com/thing:3489699 To start with, I printed it out in grey resin and offered it up. It looks cool enough but a) the mounting posts were too close together as printed and 2) the bumper sits a little too low for my lifted body. I figured the whole thing would look better if I lifted and deepened it, as well as adding a direct-to-chassis mount in place of the post-style mounting to reduce flex during winching and stowage.
