Print guidelines
Here are print guidelines for you to follow in order to have decent success with printing parts:
| 3d printing process | FDM (fused deposition modeling) |
| Infill type | Support cubic, Grid, Gyroid, Honeycomb, Triangle or Cubic |
| Material | ASA, ASA-CF, ABS, ABS+, ABS-CF [1] |
| Infill percentage | 25 - 60% [2] |
| Layer height | 0.2mm, recommended |
| Wall count | Recommended: 4 |
| Solid top/bottom layers | Recommended: 5 |
| Extrusion width | 0.4mm, recommended |
Side notes to the print guidelines
[1] PLA, PLA+, and PETG are also considerable filament choices. However, take into account that soldering iron radiates some indirect heat. The usage of less temperature-stable filaments may result in part deformations over time. It is recommended to use PETG ir ideally - ASA or ABS at least for “arm” and “iron mount” parts.
[2] Consider using 60% of infill for build plate part to ensure it's not sagging over time and 25-40% for all other parts.
A wall count of 4 is an absolute must to ensure the structural integrity of the parts.
File naming for printed parts
The parts use this naming convention:
| Primary color | These files will have nothing at the start of the filename. Example: buildplate_x1.stl |
| Accent color | Files have “[a]” to the front of any STL file that is intended to be printed with accent color. Example: [a]_bushing_x1.stl |
| Count of parts | Files have “x1” to “x4” at the end of any STL file. The number represents the count of identical parts to be printed. Example: [a]_m5_1mm_spacer_x4 (In this case you will need to print 4 identical spacers). |
| Revision number | Files have i.e. “_r1s” suffix at the end of any STL file. This number is file revision number. |
