Description
Inspired by my wife's desire for some fun additions to the play sets she brings to train shows and book signings, I decided to try my hand at creating a new version of this adapter designed to connect bricks compatible with LEGO Duplo up to your favorite brand of wooden railway.
It's heavily influenced by various other similar adapters that have been on Thingiverse for years, but designed from the ground up with precise measurements for the greatest brand compatibility, more kid-friendly rounded edges, and more internal structure to reduce the number of large bridges so you don't need to use support material when printing.
This was designed in Onshape, so you can access the design here, and edit per the CC license:
Printer:
Openbeam Kossel Pro
Rafts:
Doesn't Matter
No
Resolution:
.2mm
20%
Notes:
This was designed to print with no support, but a 2-3mm brim (both inside and outside) will really help with bed adhesion for the first few layers, which are very thin to stay within tolerances of the plastic brick of your choice.
