I tried to teach myself CAD... never again... anyway!
After much trial and error (mostly error) I gave up and grabbed a cereal box and some scissors, and went all primary school to finalise the body shape for Leopold the Leopard!
This is (finally) a scaled down version of the Feather that lives in the parts boxes in the garage.
Leo is a frint hinge flipper powered by a 25kg servo, driven by generic 1000rpm motors spinning some Banebots 23/8" wheels, fed some juice through BotBitz 10a ESCs (gave up waiting for VEX29s to be stocked by literally anywhere) from a 3s 35C 1500mAh, went a bit overkill on the battery front.
The base/back/thing is recycled steel shelving, cut from one piece as a net and folded via extreme precision beating with a hammer, there are 2 L-brackets from 1mm steel to strengthen the top corners. Sides/top is recycled PE pipe, but due to skip contents limitations, may have to be MDPE for weight savings, the only HDPE I have 'liberated' is around 18mm thick and subsequently not much use below Feather.
Next up is the flipper arm, a strip of 3mm Aluminium of unknown scrap-pile origins, hinged at the front (currently going to be a brass door hinge, but open to suggestions here) and tucked behind the leading wedge which will be a filed piece of 6mm Aluminium of similar origins to the other bits..
Now the good bit, piccies!!
Not shown; 7v BEC or ESCs because they aren't here yet, the sides, because I'm still looking, and the leopard print vinyl wrap, because it isn't quite ready for that yet.
