I designed this 3D printed grip for my SPAMF, which was in turn designed by Gavin Fuzzy. The current version friction fits, future versions may have a more elegant solution. I am releasing these files under the CC – BY – SA license. What this means in plain English: You may print this, sell this, remix this, and post your remix, as long you attribute me and use the same license (CC-BY-SA) in any derivative work. You may do all of this without paying me a dime, however if you do start selling these grips consider buying me a cup of tea. Thanks!
