Universal Filament Spool Holder - over Ender 3 top bar!

cults3d

I really loved this project created by Pitoo67 and originally from in_the_garage so i decided to create a LIGHTER (print in much less time and use much less filament ) but still 100% working filament spool adding ONE thing it can NOW be placed on top bar of ender 3 ( the bar is 20x20 so probably it'll fit fine for other printers ) ! Beside the original design I made these different parts: main_part.stl like the original base but with less " esthetic " design, more functional ! ender 3 top_insert.stl this will allow you to place the base on top of ender 3 ! main_part_balance.stl this little piece ( you need 2 ) will be needed cause it will balance the structure , denying the tipping on the sides ! Another cool characteristic of this project is : TOTALLY AVOIDING any sort of SUPPORT to be printed !! That's why i re designed it , you dno't need support at all and this mean : faster print and less filament to be used ! all these parts will snap into each other and if you encounter some problems it might be due to allowance which might be different from printer to printer, in that case you will just need to file it a little to let it snap perfectly ! You will need to buy 4 Roller bearing 8x22x7 ( https://www.amazon.it/dp/B07ZRGVQX6/?coliid=I2LSQYYPMX0794&colid=2I3DIJP83O9UW&psc=1&ref_=lv_ov_lig_dp_it ) ABEC means the quality of those roller bearings.. for this project you can take any abec : 5, 7 or even 9 !
