I've created this site to collect in one place information which can help any engineer or maker in creating new designs. Site will be aimed at mainly additive manufacturing but it will also gather core knowledge any maker or engineer would usually search for while designing next best thing

Aluminium profiles - currently THE material to build your printer, CNC or any other contraption with. Unfortunately lack of clear standards and manufacturers innovation lead to creation of few variants with some distinct pros and cons.
Designs created for One profile may fail when u use different one or you will need to change some components to accommodate features of specific profile type.
Currently in common use (3d printing construction) there are 4 main types of profiles:
| Thread | Drill size for tapping standard metric threads | Clearance hole |
| M1 | 0.75 | 1.2 |
| M1.2 | 0.95 | 1.4 |
| M1.4 | 1.1 | 1.6 |
| M1.6 | 1.5 | 1.8 |
| M1.8 | 1.4 | 2 |
| M2 | 1.6 | 2.4 |
| M2.2 | 1.7 | 2.8 |
| M2.5 | 2 | 2.9 |
| M3 | 2.5 | 3.4 |
| M3.5 | 2.9 | 3.9 |
| M4 | 3.3 | 4.5 |
| M5 | 4.2 | 5.5 |
| M6 | 5 | 6.6 |
| M8 | 6.8 | 9 |
| M10 | 8.5 | 11 |
| M12 | 10.2 | 13.5 |
| M14 | 12 | 15.5 |
