About this 3D model

I made a leveler, isolation and glass blocker for my heater bed. for using it, print 4 times the STL. the square block is for blocking the glass on the heater bed. the others, for making isolation and prevent thermal dicipation. for ABS, I start all heater at same time and I start my print after only 2-3 min ( 240° and 75° for the heater bed ) This thing was made with Tinkercad.
