3D Printable Barrier Replacements - Purdue SIGBots

[Max_Johnson03]

Hi All!
The Purdue SIGBots have hosted 2 VRC competitions, with our VexU competition this week, and have been having lots of barrier pieces break during this time. Although we’ve heard that you are able to get these replaced, we found it was easiest to just 3D print our own replacements. We’ve shared these with some people but figured we would make a post for everyone.

Below are 2 pieces of the barrier that we remodeled to be better suited for 3D printing. We’ve been running these on our personal practice field, and have not managed to break them.

Barrier Center:

3dPrintedFieldBarrierCenter.stl

Barrier End Cap:

3dPrintedFieldBarrierEnd.stl

3D Printing:
4 Perimeters, 3 Top/Bottom Layers, 20% Infill (we run this with PLA and no issues)

I know it is late in the season but I hope this can help some people.

Here are photos of 3 month old ones on a practice field.

I posted a Q&A for these yesterday, and it was ruled now that they’re able to be used in competitions if needed. Congratulations EPs everywhere!

@bkahl would you be able to rename this post? Either remove “not” or just take out all of “Not Comp Legal”. Whatever you think is best.

These are now legal for use at competitions. Emergency Use of Replica Field Elements : Robot Events

Sure!

Only @jpearman beat me to it

This is awesome, thanks! Is there any chance you’ve created the tee piece that holds the elevation bar? Ours just snapped over the weekend and we need it to send with the team hosting skills at state.

I modeled a replacement and it is posted in this thread:

Over Under Barrier Brackets for 3D Printing

I recreated the plastic connector brackets for the barrier to make them easier to 3D print. I’ve had a couple of them break with our trailer equipment. Here they are if you find them useful. over_under_barrier_connectors.zip (1.1 MB)
