New Crash Barriers, And They Are 3D Printed! 

5-minute videos are perfect but definitely no longer than 10 minutes each. It helps when you come back to a how-to video after a few weeks when you need to look for a specific instruction. I have an Ender 5 S1 printer and I like it. I have printed stl files from thingiverse and they work great. However, I have been taking Autocad classes for 7 months and am going to create my own stl files later this month.

Just found your channel and subscribed. New to this hobby. Thanks for doing these videos. Really enjoy watching them.

Great video and build. I vote for individual videos with details and especially printing tips.

Well Peter, I gave up on the crash wall prints. I printed about 40" of the wall. The tolerences are really tight. So much so that I had to sand the dovetails to open them up and even with that I still had to pound them together with a hammer. Not good. The clips had to be pounded it to the bottom which is good so they wouldnt come out. Then the trouble started. Trying to put the wall on the track resulted in me fumbling around enough to break the fragile articulating seams between the "pillars." The upper fence piece printed perfect except for having to sand the tabs down in order to get them in the slots in the wall. Guess my filament (Inland from Micro Center) or my printer or the guy that pushes the buttons is a little off. I appreciate the help and suggestions you gave. They were dead on. Keep it up, can't wait for the next videos.

Also, I agree with wanting to see individual vids on scenery additions with detail. That really helps.

Great job! Personally, I’d like to see videos of each scenery piece. Maybe at some point I’ll take the dive, and get into 3d printing.

Nice job. What type of 3D printer do you use?

Great video! Thanks for posting. Your timing is good as I had printed Greg's wall last week after seeing you had printed them. I only have an Anycubic Kobra so printing is slow. The wall took 4 hrs 16 min. Ugh. Then I printed the clips which printed with supports because I printed as they were from the download and I didnt change orientation in Cura for slicing. I couldnt figure out how the clips worked because they were stuffed with supports. And they broke when I pulled the support material out. So, this video comes along and straightens me right out! I hadn't printed the fence yet so the tip about printing with no top and bottom was perfect. I may have to print the clips in PETG for strength. Currently using PLA . Question, did you use supports in the wall? I accidently left supports on and that has complicated the wall print. I did print with a brim. Thanks again.

I am going to give these barriers a try. As soon as the new hot end arrives in a week.

Sweet! What 3D printer are you using? Just starting to look at them. Thanks!

Peter, how many clips do you use to attach the wall unit to the track?

Individual vids please.

Have you ever thought of selling these crash barriers? I am very interested as I don't have a 3D printer.

I have a question? How did you remove the top and bottom layers to see the infill area? I can not figure this out.
