It's just that the partnumbers are confusing. There are 6 R-7 support parts, 3 R-3 parts (of which i know 1 correct place) and R-5 and -6 (also know the placement of these). The R-7 and remaining R-3 have 'up' printed on one of their tabs, but there are small differences between them. Do i need to put the straight angled corner flush with the upper/lower surface and the R-1 squares?
