Collapsible Toothbrush Stand V2

This is an improved version of my collapsible toothbrush stand. I completely redesigned the collapsing mechanism to ensure that the telescoping sections of the stand stay extended when in use and don't collapse accidently. 

This is a portable toothbrush stand inspired by those simple holders that can store 4 toothbrushes. It collapses down for easy portability and is perfect for vacations, camping, and business trips.

The stand prints in 2 sections, a base and a top. The base includes the collapsing mechanism as print-in-place.

Printing Instructions (Standard):
I recommend white PLA or PETG (to reduce water staining) with 0.2-0.25mm layer height, 5-10% infill, and 2 walls. Print using the orientations provided.

How to separate it:
Once you have the stand printed, there are 3 sections of the telescopic mechanism that need to be released. Firmly press from the bottom of the base to release the three sections (pressing from the top of the base can also help).

Installation:
Fit the center of the top piece to the center telescopic section and use superglue to make the connection.

How to use:
Push the telescopic sections from the bottom of the base upward. Then twist each section counterclockwise to keep the stand extended. To collapse, just reverse this process: twist each section clockwise and push the sections together.

Happy Printing!

After using the original stand for a few weeks, it began to collapse whenever I bumped into it because the friction-fit wasn't tight enough. So, I completely redesigned the stand to remove the friction-fitting element. Instead, I added a locking mechanism that keeps the stand extended when in use. 

The image below shows a cross section of the improved design. Specifically, the addition of the three bumps and the recessed grooves allow the telescoping sections of the stand to twist into place, keeping the stand extended when in use.
