searching on thingiverse and other sites I haven't found this replacement for the geeetech g2s, and its also useful for many upgrades, so I have designed it in fusion 360.
this holder is for lm10uu linear berings the inside is 19,4mm , should feet without problems 19mm bearings, if it's needed more tight just ask me and I'll upload the changes :).
testing now with 3dprinted style igus bearings, more photos soon.
I suggest to print them upside down as in the photo, in orther to make the inside better.
2 shells, 30% infill, petg or abs for better results
