How would you attach bearings to the extrusions? Also, wouldn't that be heavy compared to just printing the sides?

I see how the flanges could help with alignment, but is adhesive necessary if the bearings fit with a close enough tolerance?bernard wrote:The flanges can help with aligning the bearings with the chassis and give an easier surface for applying adhesive.sciencecat42 wrote:Why not just normal bearings friction fit into the drilled holes?

Re: Materials and 3D Printing?
No. I got away with unglued bearings throughout the battery buggy season last year . I just used a bunch of hex nuts and washers to smash the stuff together. It worked ¯\_(ツ)_/¯. I'd still use adhesive in the end, however.sciencecat42 wrote:I see how the flanges could help with alignment, but is adhesive necessary if the bearings fit with a close enough tolerance?bernard wrote:The flanges can help with aligning the bearings with the chassis and give an easier surface for applying adhesive.sciencecat42 wrote:

Re: Materials and 3D Printing?
You shouldn't need to glue the bearings if you've drilled/printed it properly. Also, when I'm attaching my bearings to the bearing block, I normally have to use a clamp or a vise grip. That's how tight it should be.MadCow2357 wrote:No. I got away with unglued bearings throughout the battery buggy season last year .

Re: Materials and 3D Printing?
What is a connector? I thought you just print out the two sides of the frame and then use the axle to connect the sides of the frame, with a bearing in the hole of the axle to reduce friction. How does a connector work in this situation?PM2017 wrote:3d printing connectors, using cf rods to construct the chassis.
