Thomas Minis Brio Style Train Tracks

thingiverse

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) Print Settings Printer: Monoprice Select Mini Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: .2 - .4 Infill: 20% Notes: Most parts can be printed flat, bottom down, without support or raft, with the following exceptions: Acc_Connector: I printed in groups of 8 or more together on a raft. Acc_Buffer: Printed bottom down, with supports everywhere. Puts a couple between the horizontal bars. Pushed right out with a screwdriver. Post-Printing Assembly: If you find the connectors to be a bit tight when pushing them down on a piece, try to push the connector in from the bottom, or the piece down onto the connector.
