Filament reel dispenser

3D model description

This is a filament reel dispenser, composed of eight parts, with two assembly versions, either by threaded rods or by pins.

Version 1:

2 supports, 2 rollers, 4 wheels. To assemble everything, you will need: 2 8 mm threaded rods that you will cut to the length of your choice, 4 M8 nuts, 4 608Z ball bearings (22 x 8 x 7) and 4 40 mm pins, which will act as pins. The threaded rods must be drilled in their axis at 1 cm from their ends.

A little DIY, certainly, but in the end, a very practical accessory, which avoids having the coil resting on the printer, and with this system, the angle of entry of the filament into the extruder is impeccable.

Version 2 :

2 Supports, 2 rollers, 4 pins, 4 bearings 608Z.

I modelled, for the non do-it-yourselfers, a pin that replaces the threaded rod, just put one in each bearing, and that's it.

To optimise the adhesion of the coil to the rollers, simply glue a flexible coating strip for the bottom of the drawers, sold as a GSB roll, especially at LM. Once done, there are no more slippages between the coil and the roller. The process is very smooth.
