Out of my friends, I am usually the one that has to roll joints. So when I came across a joint roller, which cost too much to my liking, I decided to design my own. Print the parts, assemble and roll your own joints.
Simply put your filter, tabacco and herb. Close The device and roll all of the contents together. Slide in the rolling paper from the top and roll it in. Don't forget to wet the glue on the paper before fully rolling it in. If that did not make any sense, watch the following link:https://www.youtube.com/watch?v=ht-RRSx2jfw
If you have any feedback, let me know. Suggestions on the belt are also more than welcome!
To complete the assembly you're going to have to print:
1x Connecting body
2x Rotating Body
2x Roller 110mm
You can cut the belt out of a large soda bottle label, put the end on the marked line and flue together.
The belt was printed using TPU 95-A at .1 mm layer height.
In order to get a flexible sheet, i used 80 - 85% extrusion rate and upped the outline overlap to 45%.
Print with one perimeter. The low extrusion rate makes the perimeters not bind to each other properly. The higher overlap with the 1 perimeter should work.
I had to do a bit of sanding to get rid of some leftover supports. But other than that, none is needed.
In order to assemble, start by making your belt (2D print the template on a 1:1 scale and use it to cut out the correct shape or print the belt STL using TPU and glue/solder together) and place the belt around the rollers.
Put the rollers into the rotating bodies. One of the pegs on each roller is shorter than the other. Put this one in the Rotating body last to prevent breaking your parts. I slid them in from the underside of the circle with the peg.
Put the rotating bodies together and connect this subassembly to the connecting body.
