About this model

(4-fin version removed because it's missing part of one of the bolt holes.) Updated with v2b and v2b 4-fin versions. These versions fit on a smaller build plate and are better overall designs. Unless you need the older (v2) version, I recommend using one of the new ones. This is a 3d printed end support for a launch tower for 38mm high power rockets. I have flown from this tower with up to a Loki J1026 and set multiple world records with it. This launch tower is designed to slip over a standard 80/20 1010 square launch rail, so you can use it at any launch without any additional equipment. Be sure the check the fit onto the 1010 rail as some have finishes (or other things) that make their dimensions slightly different. Use at your own risk. For the 29mm version and pictures of what the ass…
