CTC A13 Spool Holder Arm

If You have a CTC A13 you will know by now that the build quality if very poor. One of the first parts to break on my A13 printer was the spool holder. I printed the excellent Ball Bearing Spool Holder posted by vivamus3d on Thingiverse: https://www.thingiverse.com/thing:4576421 . The problem is that the pressed steel spool holder arm was too flimsy to take the weight. In addition, the original M3 threads in the frame had stripped. I have created a spool holder arm to replace the existing steel arm. There are 2 versions: V1 uses the existing top 3mm screws. V2 is in case the original threads have stripped. The frame can be drilled horizontally and the spool holder bolted through the frame with long M4 bolts and washers.
