Nice combination of 3D printing and traditional pinewood car hand-tools too!
Genius! Love the enclosed 3D printer.
Love the video. Super informational. Keep em coming please!!!
Glad to be here Terrence……
Great video, easy to understand!
Great video, thanks for posting!
Thanks for watching!
I am hoping to buy your wheel holders
Really enjoyed watching your videos on this. I do have a couple questions. around 2:15 you mention building strong parts, but I didn't see what % Infill you recommend other than a few images of prusaslicer. I saw 70 and 50%. Any reason to go higher than this for PLA?
You also mention generating parts with 4 or 5 parameters at 2:19, but I don't know if I need to be worried about this or not? I'm new to 3d printing and am excited to give these a shot!
I tried printing the outer wheel holder and the tolerance was too tight. Ended up scratching up one wheel pretty significantly :(
Any tips on how to loosen the tolerances up on the outer wheel holder?
I am trying to make the balancer today and will report back my findings
Do you offer in person classes for kids (and tag along adults)? 😁
Not yet.
I do belong to SnoCo Maker Space - and can teach classes there. They have oodles of 3D printers and laser cutters, and I know they want to do more kid outreach. I am in the process of putting together program for said classes - but it'll be a few months out. I also would want to make sure that the home built laser cutters have proper safety cutoffs and such enabled instead of relying on the "Dang - don't look into laser with remaining eye" warning label...
@@AMakerDad keep me posted. My friends’ kids may be interested.
can you explain how you use the chucks to polish the wheels?
We just freehand polish the wheels using a nail file or the Tamiya file Chuck the wheel up and mount it I to the drill that's clamped to a table, power up the drill and use the nail file to touch up the outside circumference and remove sharp edges.
Wow, these cars are a lot more complicated than I remember! (Never made one, I just remember seeing them. Girl Scouts didn’t do this…darn!)
Our pack (pack427.org/about/) is co-ed and welcomes boys and girls from K-5! The Wolf girls had some fast racers this year.
Also, being in an area where so much of the workforce is in tech (Amazon, Meta, Microsoft, Google) it's not unusual to see 3D printed trinkets in my youngest's birthday gift bag or candy flinging robots for halloween during COVID. It's really inspiring to see so many young kids get into science and engineering early.
Nothing is preventing Girl Scouts from doing this beyond no one taking charge and doing it! I personally coordinate and run our Girl Scouts local service unit derby which includes all Girl Scout Troops within about a 7 mile radius, making it a far bigger event than the local individual Cub Scout Packs derbies. If your service unit can't afford the cost of the track, talk to the local Cub Scout packs, you will likely be able to find one that will lend you their track for a nominal fee (or even free) or in many cases they might even offer to run it for you or help you run it. You might even be able to coordinate with a local Cub Scout pack to run your Girl Scout derby after they run theirs that way it's all set up and ready to go, then you can help them tear it down and put it away.
