Hi, thx that model! I printed and it is really nice. In Bambu Studio I removed exhaust with vertical cut as I didnt want to print with support. After printing I understood this is your blow up mouth piece as well. When blowing up balloons with a balloon pump they ripped off when attaching them to the model afterwards. Without air in it it was no problem attaching them.
So now I want to use this on a kids party with a balloon pump, the kids suppose to not share corona bacterias directly across them and so am searching for a model for sharing along the kids using a pump.
In addition, the axis and one wheel - both parts I placed centered to each other. Using X-Y hole compensation to -0.4. After this both parts axis and one wheel attach to each other directly when slicing and printing.
Using no clue I printed multiple wheels (seeh plate two) with different hole compansation values again to fit the perfect one and found ;-). You may print two times sorry the little waste.
I try adding my very first print profile here.
Thx again the nice model.
PS: After testing now multiple car balloon models, this model here was the most biggest and heaviest one. Compared the others it had the most stable drive path.
