Dual Hot Wheels on Duplo Blocks
(The base model is of @NHSE "Hot Wheels on Duplo Blocks" https://www.thingiverse.com/thing:857714 )
This expanded hot wheels duplo adapter give twin tracks mounted in parallel. This post includes from a 5 wide up to 16 wide models (# of duplo studs). If you need to go beyond 2x16 I have included the fusion 360 model for you to customize further.
The main drive for this model was to give a solid surface for the the hot wheels track thrid/quarter loop model (https://www.thingiverse.com/thing:2779107).
Full loop BOM:
3x - Hot Wheels Track Quarter Loop (Thing 2779107, printed in ABS)
4x - 12" Hot Wheels Track
1x - Dual Hot Wheels on Duplo Blocks (Printed in ABS, Any width 2x5 or greater)
NOTE: If you are using this for the full loop the wider you go the more flex you will get in this part. I have beefed up the half height duplo side of this part and also made a full height duplo version as well.
Update: 2024-11-18, Removed Step and Fusion files due to online sellers using the designs to sell on platforms like Etsy. Sorry to future visitors of this page. Sharing any models going forward will be rare and sparse due to these abuses.
