Spool Cart by Unicone Design: 2022 January Steven S. This product is designed to be a filament dispenser for FDM printers. It can hold 3 tiers X 5 standard size filament rolls for a total of 15 rolls. For filaments sensitive to moisture, an alternative assembly calls for the dry box to be placed on the top and bottom tier with the middle tier removed. Material: A) 1X Target 3 Tier Metal Utility Cart - Brightroom. https://www.target.com/p/3-tier-metal-utility-cart-brightroom/-/A-83961087?preselect=83499914#lnk=sametab $35.00 USD. B) 3X PVC Pipes (42mm diameter cut to 420mm length) PVC pipe was marked with 1 1/4" diameter. Adjust if different size PVC is utilized. C) 15X PTFE tubes cut to appx 10-15cm according to your need. Printable files as followed: Spool Cart (ALL).stl This file contains: 15X PTFE Tube Holders 24X Wedges 2 X Top Tier Ends 4 X Tier Ends Assembly Instruction: Assemble Utility Cart as described in the instruction. Place Top Tier Ends on the top layer with PVC pipe connecting the two ends. I do not have issues with filament rolls interacting with each other without roller or separation spacers. Use the printed wedges to secure the Ends position. If so desired you can add those between the spools. Do the same for the bottom two tiers with spools at the two ends. The PVC pipe can be lifted and removed from one end when spool change is desired. Place PTFE holders on the front end of the carts at an equal distance. Use the wedge to secure their positions. I recommend the filaments be fed from the bottom of the spool upwards towards the PTFE holder to avoid tangle. It's a toilet paper roll orientation debate. Assembly Instruction 2: For filaments sensitive to moisture. During assembly of the cart, remove the middle tier. Assemble the rest of the cart and find the appropriate dry box with a filament inside on the cart. In this configuration, no 3D print files are needed but the cart will only be able to hold 10 spools. I hope this helps you organize your Filament spools. Keep Innovating, Keep Printing.
