About this 3D model

this is a ladder for a Hamster Pipe. it snaps tide and should hold very strong, but in case i have added screw holes... but i dont needed it. its teste by my hamster and he like it very mutch. i have added it and he instantly tested it! ;o) printed without support, but with extra fan and 50mm/s at layer high: 0.2 with PLA. i think the hamster pipes have all the same diameter, cause i buyed different pipes and all fit together... so i think others can use it also...
