Makergear M2 Scribbler Attachment

STL files for this are available at Thingiverse and can be found HERE.

This is a drawing attachment for my Printer. I saw this thing call the Axidraw one day and it got my brain a working so here’s yet another quick little project to add some more fun and versatility to the M2.  It’s just a simple bolt on attachment to hold a sharpie or any drawing implement.

Here’s a picture of the first test. I still need to play with the speeds but so far it works pretty good. This was just outlines but I did try one with 100% infill and got a little to much bleed with the sharpie so I need to find a fine tip marker and play some more.

…and of course The video of it in action (video is 4X normal speed and it cuts out the last few seconds as my memory card was full.)

Outlines Only with thin tip markers.

100% Infill

The thin sharpie works pretty good. The tips don’t have much give like their fatter big brothers so there were a few sacrificial lambs in the process until I remove all the unnecessary start up moves in the startup g-code.

The 100% infill isn’t perfect as it missed some spots but I don’t have the tip size factored into S3D yet so I still need to do more testing. I’ll probably redesign some things to make it the marker a bit more steady as it does flex about a little bit in the current state. I don’t know how usefull an attachment it will be but it’s fun to play with anyway.

I designed a spring loaded Ball point attachment today to try out next.

It’s ugly and needed some sanding, but it was a quick print with some $11 Chinese filament I haven’t even bothered to dial in yet.

I might need a stiffer spring but so far it’s going pretty well.

The finished picture… I think if I use something like a G2 gel pen (and a better surface than the aluminum bed) it will write a lot better so it’s back to the CAD to redesign the pen part around a G2 cartridges next.

The Gel pen works much better… was able to play around with text that looks like handwriting and it works pretty good. I’m going to be the hero went it comes to Christmas cards this year… “Sure honey I’ll fill out all of the cards this year.”

I still don’t have the perfect setting for fill yet but it can do some pretty good detail. This was just a line drawing I found on Google. It was converted to an SVG, imported into TinkerCad and then exported as an STL.

I’m deeming this one a success and now I can move onto my next Attachment.
