Small spool holder for Mendel90

September 10th, 2013 Leave a comment Go to comments

After I completed building my Mendel90 I was a bit disappointed when I found out that the spool I had (bought from ultimaker site) was smaller than the spool holder. So I placed the spool on my desk behind the printer and never really bothered to solve the problem. Every now and then during the printing I would manually unroll filament from the spool so I don’t stress the extruder motor.

Well a couple of days ago I was browsing the reprap forums and found a nice extension that solved (well sort of) my problem. Fellow reprapper GerdH created a neat extension design to support multiple spool holder sizes. I downloaded the .scad file, compiled it, sliced it with Cura with my settings and printed it. I had to run to the nearest hardware store and get a set of four screws with nuts. So within few hours I saw the post the spool holder was installed on my printer and its working perfectly. No more manual unrolling of filament!

    I am *so* envious. I would love to have a 3D printer but will have to wait awhile longer I think. I’m not sure how long it’d take to get everything dialed in to where I could actually *save* time building a robot versus just using aluminum stock, wood, and a hacksaw… but still.

    Hey Michael. Nice to see you on here! Your point is valid, sometimes it just makes more sense to buy something stock. However, the whole experience of having a design in mind, then design it in the CAD program, then print it and finally assembly it, it HUGELY rewarding.

    Michael I would be more than happy to print out a part or two and send them to you! Just send me the STL files and I will send the prints back to you. Let me know!
