Modified the rollcage to be a bit more solid and have less openings. Means a little more weight but also means less annoying support material.
Added screw holes throughout the chassis for mounting various armour upgrades.
Also replaced the stand with a better version that should prevent the bot sliding off.
Found an issue with Rollcage. He had a knack for getting stuck on his back, in the vertical position.
To fix Rollcage, this version has a tapered rear end now to help stop him getting stuck.
I also added some screw holes in the rear of the chassis for mounting some armour. I used some 1mm Lexan sheet, cut to size with some tin snips.
This is my 3D printed design of a bot used in our 150 gram Antweight combat league. I've named him Rollcage.
Rollcage is about as simple as you can get for an antweight bot. He is a standard wedge/pusher bot and is perfect for anyone looking to get into some robot fighting. We will be using the Rollcage design to make a few spares for newcomers to try out and fight with.
This bot leaves a little for you to customize as far as the internal components go but please use this list of components that I used as a guide to get you started:
- Print the chassis and two of the offset microgear motor mounts. Add supports in the chassis and motor mounts as required.
- Carefully break away the support material.
- Give the parts some acetone vapor treatment (optional).
- Wire up the motors to the ESC and connect their supply to the battery connector and power switch.
- Add a power on LED if you want. (With an open top, the lights from the ESC's and reliever provide more than enough power on indication).
- Carefully put in the motors and ESC's inside the chassis. Secure the motors with the motor mount clamps. Use a couple small self tapping screws to hold it down. I used spare screws that came with a couple standard size servos.
- Connect the receiver and mixer to the ESC and insert into chassis.
- Hold everything down with some hot glue if required. I found that everything sat pretty snug inside and no glue was necessary.
- Connect the battery and insert into chassis.
- Attach the wheels and you're done!

Also used brim to prevent edges curling up.
