About this 3D model

This is a lightweight, exstensible reel feeder. It can be extended both vertically and horizontally.- Module with 1 bar can hold reels up to 8cm diameter. - Module with 2 bars can hold reels up to 6cm diameterEach module requires 2 bases, 2 main beams and 1 or 2 hole beams. Each additionnal horizontal module requires one base instead of 2.Horizontally, 1-bar and 2-bars modules must be interspaced.I would not recomment putting more than 3 floors vertically (denpending on weight of reels and required stability)Each module requires additionally 1 or 2 bars ~17cm long with diameter lower than 10mm (made of wood on photo), with a clip or a nail to stop it from getting out.I would recommend at least 20% filling with isotropic type (cubic for instance), to improve emchanical properties
