Kelsier Daggers Holster (Mistborn)
I designed a holster for the Kelsier Daggers model made by purplehazey (https://www.thingiverse.com/thing:4917831) for cosplay. The idea is to use straps to attach it to your leg, you can attach it to a belt as well but since the daggers are pretty bulky I would not recommend this.
I made this using Tinkercad, so it is super basic but works pretty well :)
