Hi Magnus.
Maybe:
* 32199.dat, 32200.dat, 32201.dat, 32202.dat, 32235.dat, 32580.dat Technic Axle Flexible various length - uses lots of "axlehol8.dat"
* 32062.dat Technic Axle 2 Notched - uses axlehol8.dat, axlehol2.dat, axlehol9.dat
* 99008.dat Technic Axle 4 with Middle Cylindrical Stop - uses axlehol8.dat, axlehol2.dat, axlehol9.dat, axleho10.dat, axlehol3.dat
* 47330.dat, 47300.dat and maybe other parts from Bionicle with ball socket uses various "axlehole-type" primitives for ball support.
