from the project of my first heavy duty spool holder I have remixed it with a new solid version intended to work with more spools,u will need many bolts and a metal or wood bar, my work is intended for a bar of 1,6cm diameter but if u need just ask and I'll design a block for ur bar,
yeah a block, I have made many screw blocks for the bar in order to let it not rotete.
disclaimer: is a big object so in order to make it I think you'll need about 180-250grams of filament, I've made it at 0.2mm height but should also go for 0,3 , I suggest 15% infill,
you fill need a file, for the holes, i made them 5,30 to wedge the bolts, or if u want,u can screw them in, it also works
I made this for my ctc,but if I'm not wrong every replicator dual with wood shell sould be the same, if not and there are differences in dimensions, let know
other parts needed:
4pcs M5 x 25mm (back part 2boltsforeach side)
2pcs M5 x 30mm (middle part)
2pcs M5 x 40mm (for the front bar)
1pcs m3 x 20mm (to joint the printer with one of the holes prearranged for the standard PTFE tubes)
4to6pcs M4x2mm (depends on the number of blocks on the bar)
a bar, metal or wood , about 40-50 centimeters.
left and right parts are different, except for the second spoolbase part, the noblocks and the other locks, whish u willneed toprint 2 times each
soon I'll make an upgrade to use ptefe tubing and probablyfor 4ptefetubing ,for fast changing filaments
