Thomas Minis Brio Style Train Tracks by j4c3

Last crawled date: 3 years ago

I could not find any printable tracks for the Thomas Minis trains, so I set out to create some, and learn more OpenSCAD along the way.
These started as modifications of the Remixed projects, so some code might be lifted directly, but as the project went along, most things ended up adjusted or rewritten in one way or another.
There are many (most?) of the available, modern Brio pieces recreated here, and a few non-standard parts. My print bed is only 120x120, so larger parts are available in the full size, and split into smaller pieces.
I tried to name the parts consistently, in a way that conveyed adequate info about them. Sections are separated by underscores ( _ ), and within those sections, info is separated with dashes ( - ). Sections marked with an asterisk ( * ) are not always present.
(PartGroup)(PartSubType)*(SplitPartIdentifier)(Dimensions)(BrioIdentifier).stl
An Example using all sections: QuadCurve-Cross_SmR_PART_Xof4_L1.5-C.25_X
PartGroup: QuadCurve-Cross
PartSubType: SmR (small radius)
SplitPartIdentifier: PART_Xof4 (broken into 4 equal parts)
Dimensions: L1.5-C.25 (straight Length - Circumference)
BrioIdentifier: X
All dimensions are defined toward the top of the SCAD file, but for naming the important values are:
L - Length = 110mm
LgR - Large Radius Curve = 150mm
SmR - Small Radius Curve = 67.5mm
I test printed many parts along the way, but in their final form, the following pieces have been test printed:
Acc_Connector
Curve_SmR_L-Str_L.75-C.125_O1-P1
Curve_SmR_R-Str_L.75-C.125_O1-P1
DoubleCurve_SmR_L-R-Str_PART_1of3_L1.5-C.25_T
DoubleCurve_SmR_L-R-Str_PART_2of3_L1.5-C.25_T
Curve_Double_L_LgR-SmR_C.125-C.25
QuadCurve-Cross_SmR_PART_Xof4_L1.5-C.25_X (Printed 4)
