Foldable filament spool for two sample filaments

thingiverse

I got inspired by this thing: https://www.thingiverse.com/thing:3129414 Yet, I thought to add a second sample filament holder that can be used simultaneously. The spool dimensions are too large to fit on my spool holder, which has a diameter of roughly 200mm and an unfolded width of about 85mm. Each guiding arm-section can hold approximately 100g of 1.75mm filament, totaling 200g per set. To build the holder, follow these guidelines: Print two base_ring_vXX bases Print either four arm_mod_v00 or arm_mod_v01 arms each, or if you prefer to secure filament on every arm, print eight arm_mod_v01 arms The required materials are: Eight M3x25mm screws with hex-wing heads Eight M3 nuts Four M3x16mm screws with hex-wing heads Two ball bearings 262Z (compatible with an M6-type rod axle)
