Boost Me (for free)

Your boosts help me continue to make designs available for free! Give me a like and follow if you enjoy my designs!

A simple free-wheeling toy car that fits in your pocket or bag. Check out the Rubber Band Racer here. Give me a 👍 and 🚀 if you enjoyed this 🙂 more designs and commercial rights available on my Patreon.

It'll roll effortlessly with just a light push or just blow air at it; the harder you push, the farther it'll go; rolls on it's own on a downhill.

Please make sure your build plate is clean and free of grease and oil before printing. Although it didn’t happen in my testings, there are reports of it failing near the end of the print. If this happens to you, your build plate isn’t as clean as you think it is. Good luck 🙂

I recommend using PLA-CF, they look great and add a bit of strength to the model. Other materials will work just fine.

Parts needed to complete the build:

4 MR128 Steel Deep Groove Ball Bearings

8 24x2.5mm O rings OR 8 1.4x20mm Basic rubber bands

check out BOM for links or get them from Amazon:

Bearing
O rings
Rubber band

Due to its unibody design, it could be a challenge to bigger hands to assemble it. If you’ve built my Pocket Rubber Band Racer, this will be a breeze for you, just remember that this time to install the bearings from the outside of the chassis.

Push in the bearings from the outside of the chassis

Place the axle between the bearings in the chassis and then push the wheels in from the outside of the car.

accidentally compatible with L.e.g.o minifigures hands

A most interesting project, initially I too experienced adhesion problems which I immediately resolved by slightly reducing the print speed. Upon completion, I realised that everything was indeed too fragile (printed in PLA), so I printed everything 20% larger (maintaining the original dimensions of the bearings) and the result was optimal, a super solid structure. Finally, I added TPU tires to make the whole thing more appealing

I have to reprint. right near the end of the print it fell over. I should have used some glue on the build plate but I was in a hurry as usual. the thing that kills me is that it was perfect and because I skipped a step it went barrels up. I will reprint when I get a chance and post the print! I think this is a really cool design so I will cross my fingers so I get it right!

@MakersForge

hi, same here. This happened on my A1 Mini but since I got the P1S it didn’t happen anymore. I think the Problem might be because it was a bedslinger…

I too had my first two prints fail, but I paid close attention to why it failed and I have uploaded a new print profile to help others (see "Foolproof pocket push racer chassis" print profile above). This model requires proper cooling due to the nature of its design (quick layer time, overhangs, and standing tall). The failure seems to occur during the bridge of the front bearing holes. If the material doesn't cool properly, it will curl up enough for the nozzle to knock the tall standing chassis off the build plate. To say this is an adhesion issue is just not fair. To prevent the material from curling, the profile I made adds supports at the bearing holes. The cooling is also increased slightly, speed is lowered, and I have added a z-hop to cleanly move between the chassis tubes. Overall, the model is great! I just didn't have success with the original print profile. Pressing in the rear bearings took a bit more force than the front (slight hole size difference observed).

Green PETG Translucent, great print. Thanks for sharing!

The only issue I have is the cleanup required in the bearing pockets when printed without supports.

Seriously quick! Had some curling up printing the overhangs and two of the prints failed, so had to reduce the speed but finally it turned out good.

The overall design was good. But I had trouble with the bearings. I assumed it was a press fit with the axes of the wheels, wich wasn't. so I glued them to the bearing to make sure they are using the bearings and not just spin loose in it. But now, it rolls very quietly and smoothly, but not by its own. Was it just me or is this how it's supposed to be? besides that: great job, thank you!
