Tiles. There is never enough tiles. I am always short of some bricks when creating LEGO MOCs (My Own Creation), so I am using FreeCAD and my printer to create temporary placeholders when prototyping.
The model was designed specifically for 3D printing with tolerances in mind.
For printing I recommend to start with attached FreeCAD project file and modify properties according to Printing Guide.
Parametric Size
Dimensions can be modified in attached FreeCAD project in Properties sheet.
- WidthStuds - width of the tile,
- LengthStuds - length of the tile.
Attached are exports for common dimensions: 1x1, 1x2, 1x3, 1x4, 2x2 and 2x3.
Printing Guide
(how to preserve compatibility with LEGO when printing)
There are several factors influencing compatibility with LEGO or other bricks system. Building capabality is mainly based on:
- friction, and
- spacing.
Friction is maintained by
- studs and tubes diameter,
- inner walls thickness, and
- auxiliary reinforcments.
Spacing is maintained by
- play tolerance offset.
With common 3D printer, we are not able to match required precision to create adequate friction, we can only approximate.
Basic printing parameters
- Material: PLA, PETG or ABS
- Layer Height: 0.15 or 0.2, both is OK.
- Perimeters: 3, print outside perimeters first
- Infill: does not matter
- Supports: not needed
Model parameters
Relevant for this model. The model does not have studs, tubes or hollow studs, so it is easier to calibrate.
| Parameter | Description | My MK4 (kit) | Your printer? |
| WallThickMod | Wall thickness modifier | -0,1 mm | ? |
| PlayTolerance | Play tolerance offset | 0,2 mm | 0,2 mm |
Play tolerance offset of 0,2 mm is a LEGO standard, there should not be a need to change that.
Beware: Parameters can also slightly differ with various materials, even different color from the same brand can influence the result.
What to do when
- The printed brick does not hold on top of original LEGO brick (walls are too loose) - add to WallThickMod in increments of 0,05 mm.
- The printed brick cannot be placed on top of original LEGO brick (walls are too loose) - substract from WallThickMod
Share your printing settings and parameters for your printer. I will update the table. Exported files (3MF, STEP, STL) are with parameters for my MK4.
