Lock Step Tube Roller - Print in Place

This is a ***print in place plastic*** tube roller for things like toothpaste. I plan on making this a non-candy option at Halloween and for that I wanted no detachable parts that could cause an ingestion hazard. It also needed to lock to prevent the tube from unrolling.

This design uses the flexible attributes of the length to provide give for the handle to turn to the next position. It will get a little tighter after the tube is inserted as that will slight blow the main shaft. It uses an 8 position hold pattern with 4 balls to provide the locking.

## VERSION 2 prints have these attributes

+ closer tolerance on the end. It may be too close for some users. I left V1 there.
+ Dots on the support to better hold to plate
+ One additional internal support on the cone. This is to prevent the cone from falling over before getting to the second support in the cylinder passthrough.

I made it in several formats
+ Just the roller
+ Roller with Hanging ring “RIGHT” handed
+ Roller with Hanging ring “LEFT” handed

all versions with pre-rendered support bar and without
Sizes 40, 50 and 67 seam to be a good selection for what I had on hand.

## Left or Right hanging versions
The left and right will be up to you based on which direction you roll your tube. If you want to hang it the tube should sit between the spindle and the bar when hung.

+ Prints great in PLA with no supports if you use the built-in support model. I have not tested it in other…
