This is a customizable tube I designed for storing my Yaesu ATAS-25 portable vertical antenna and all its accessories. It is 106mm O.D. and 90mm I.D. The thread is a Metric 42x3.0 thread pattern. I chose this as a compromise between coarse quick to unscrew threads and fine threads to help keep water out.

It is printed from Creality ASA filament to resist the elements and UV, and the gasket(s) are printed from Creality TPU 95. I printed all parts on my Creality Ender 3 V3 CoreXZ and my Creality Ender 3 V3 PLUS. All parts fit both machines.

I have included .3MF files for all parts as well as .STL files for use with non Ceality printers. To make it more customizable, there are options for 230mm tall segments as well as 130mm tall segments and a top cap with or without a built-in storage cubby for small parts/paperwork.

I plan to test this designs water resistant properties soon, but it will at least resist rain and dew. I am going to test it against IP67 criteria just for fun.

I printed the 230mm bottom, and 2, 230mm middle tubes plus the top with storage and top plug and one gasket to house the Yaesu ATAS-25 antenna. I used clear silicone RTV to seal the joints permanently on all tube sections except the top which is gasketed.

A rope can be attached to the tube using the attachment points on the bottom and top. I plan to use a carabiner at least on the top section so it can be easily removed to unscrew the top.

I used tree supports on build plate only and only critical areas for the "Mid" tubes. no other supports are necessary when parts are oriented as designed on the build plate. These can be printed from any ridged filament however, IF USING ASA MATERIAL I HIGHLY RECOMMEND A 10MM BRIM TO KEEP THE PARTS FROM WARPING OFF THE BUILD PLATE. THIS PROVED KEY FOR MY MACHINES!! Zero warp on either of my printers this way.
