Mytechfun test objects – Bộ mẫu thử filament

One of the main subject of Mytechfun Youtube channel is filament testing. Regular test specimens are used, so the results are comparable with those recorded in earlier experiments. If somebody wants to repeat similar tests, he can download these test objects and 3D print them. In Mytechfun testing, all are printed with maximal number of walls (or perimeters or shells). The “no hole” version needs a special holder, which in my case is CNC machined (I used CNC services by PCBWay or you can use SLM metal 3D printing services by JLCPCB). STEP files are available too. For some of them you will need a D SHACKLE CHAIN LINK with proper diameter. 

There are versions with designed brim for better adhesion (for FDM printing) and same version optimized for SLA printing (no brim).

This is a video as example, where you can see these test objects in action:
