Lego Balloon Racing Car

thingiverse

This is a (major) redesign of the balloon jet car. The main changes are:- 1. Slimmed down body (to save weight) 2. Balloon tube moved much further back (to accommodate the lego) 3. 2 rows of 4 lego studs to allow a lego driver and steering wheel 4. 3D printed axles with cutout to allow the wheels to be pushed on (and taken off) 5. The addition of a stalk to hold the balloon up There are two alternate body STLs (car body A and car body B). A has the balloon filament support integrated onto the car body, the B version relies on an external part fitting over the exhaust. EDIT - I've changed the brace balloon ring so that you can slide it up and down the filament rather than having to cut it to size every time you change the balloon. EDIT 2 - I acquired some TPU filament and decided to remake the wheels with tyres. The 3 added files are 'left wheel rim' right wheel rime' and 'tyre' Print the rims in PLA and 4 tyres in TPU and then fit the tyres over the rims. Alternatively, particularly for dual extrusion printers, the rim and tyre can be combined for a single print.
