38mm Launch Tower
thingiverse
A redesign of Groucho Duke's 38mm high power rocket launch tower. Removed the 10/10 rail section and added a third support rail to make it stand alone. List of Materials: A little more than 1kg of PETG or similar filament. 6x #10 1-1/4" machine screws 12x #10 flat washers 6x #10 lock nuts 3x aluminum extruded 3/4" L brakets 3x 3/4" EMT conduit Adhesive backed Teflon tape. For the rocket facing side of conduit, smooth on the rocket. Print 2 of the parts (takes approx 42 hours each plus about 0.6kg of filament) Sand/file/buff/machine the EMT conduit inside and out to remove any bumps that would damage your rocket and rough ending Test fit the 3d printed parts on the 1010 rail, EMT conduit & extruded L. You may need to sand, file or Dremel a few things to get the perfect fit. Trim extruded L and/or EMT conduit to fit. Deburr the ends so they'll slide onto the printed parts (For the 64" extruded L I used, the EMT 4conduit to 60" worked well.) Sand/file/adjust the 3d printed parts as required Use 3 adjustable straps to hold it down and level. A need for some sort of Blast plate will be required,
