this tiny gravity knife prints in 3 pieces, body, blade & pin , requiring little assembly , simply slide the blade into the body then secure the blade in by inserting the last piece into the hole on the blade, its designed to be a friction fit but some glue may be required to hold it in depending on your printers tolerances

printing in 1-2h this small blade is a perfect fidget toy that is small enough to carry anywhere

If the blade is too big and doesnt slide try to reprint it and the pin at 95% scale
