I'm reposting this because I used the wrong account. This is a roller-head speargun that I modeled in Fusion 360; it can be 3D printed or even made with a CNC machine

This is a 100 cm speargun with a 16 mm bungee cord. The approximate cost to build the speargun is $80. I haven’t added the arrow guide yet, but everything is available on my cults3d profile. If you have any questions, ask me !
