Hollow Fidget Cube - Assembled with 1.75mm filament as hinge pins.

Just a different version of my fidget cube, but this one made up of hollow cubes. The original is here: https://www.thingiverse.com/thing:3576940 You'll need to print four of each cube and eight connectors. CONNECTOR2-STL is a little smaller in outer dimensions than CONNECTOR1-STL, which may make assembly slightly easier. Getting filament to insert into the hole can be tricky, but it helps to ream out the holes with a drill or other small instrument. If the filament won't go into the holes separately, you'll never get it to go all the way through an assembled joint. So ream out each hole until the filament will go through each part, then assemble. A 1.5mm hex key works nicely to get the holes aligned before trying to insert the filament. The sample part is made from Inland natural color PLA and AIO Robotics Red PLA. Printed in .2mm layer height on my Ender 3. I uploaded a matching stand. https://www.thingiverse.com/thing:3581730
