BIBO 3D Printer Filament Spool Holder Adapter

thingiverse

This is an adapter that improves on the BIBO Filament Spool Holder. It includes three parts: 1) A large flange that fits snugly around the filament spool 2) A washer that goes between the filament spool and the BIBO mounting flange on the back of the printer. 3) A smaller flange that goes between the filament spool and the end of the existing shaft. This piece keeps the filament holder closer to the back wall of the machine and helps prevent the filament from coming off the spool and getting behind the spool between the spool and the back wall of the printer. The picture of the spool of black filament clearly shows the washer on the back of the spool and demonstrates how closely the spool is held to the wall, while still rotating easily. The picture of the spool of white filament shows the smaller flange between the filament spool and the end of the BIBO spindle. You can see that it leaves no room for the spool to drift away from the wall. All dimensions are parameterized. So you will be able to make adjustments in case your filament spools are different sizes than mine. I sliced the STL files with slic3r, specifying support for the large spool. I printed the parts with PLA using these settings: 200 degrees hotend temperature for the first layer 180 degrees hotend temperature for subsequent layers 70 degrees bed temperature for all layers on the bare glass platform of the BIBO. I used the same filament as for the part itself, and support was generated for the large spool. These settings worked out very well. The PLA liked the temperatures. It stuck to the bare glass very well and came off the board very easily after cooling. The file BIBO_washer_and_flange.scad is the only SCAD file you need. It includes all three parts. Just uncomment the one that you want to print. /* NOTE: the line below is needed for all three parts * It provides the hole through the center * of each part, so that they will be able to * be slid onto the BIBO spindle */ Line 43: cylinder(h=1000, d=spindle_diameter,center=true);
