This is a holder for your bike designet to hold it perpendicular to the ground saving you some space in your house.
This model has 2 .stl files, one that has the fillets on it and the other that hasn't. The second one it's there if you feel that it's too tricky to print the first one.
Both models have in the center two holes for screws as this is meant to be mounted on the wall but you could try with tape as well.
Hope it suits your bike well and if you print one let me know how it turned out!
NOTE: I haven't printed it so I don't know how well it works but I made it from my bike dimensions so it should work well.
