Toilet Roll Holder for Gridfinity 2x2x3

If you haven't Gridfinitised your bedside table drawers yet then where have you been?!

This is a simple bog roll holder (aka toilet paper holder) for #Gridfinity.

Disclaimer #1 - the diameter of a brand new toilet roll is a little too wide to fit in a 2x2 Gridfinity, however if you use a little bit of the tissue paper first, then this will work nicely. 

Disclaimer #2 - this isn't a bog roll dispenser, e.g. bog roll will not spin around like it does in the bathroom. Just a holder that will keep your bog roll in the right place. You would need to remove the entire bog roll in order to use it.

There are TWO versions:

• STACKABLE - The first features a tapered design to properly fit the inside of your (40mm diameter) bog roll; this will hold the bog roll nice and securely, meaning that you can't remove it with one hand. At least, not without removing the holder from the Gridfinity base. It tapers from 38mm to just over 40mm.
• GRABBABLE - The second version is perhaps more suitable for those of you who may wish to remove the toilet roll from the holder with only one hand, i.e. it will just lift off. To facilitate this, the central extrusion is a narrower 36mm diameter and is much higher to ensure the bog roll stays on when you open and close your bedside table. As such this version is not stackable. I guess you could say this is more “purpose built”.

Frequently Asked Questions (aka never-asked questions)

Q. Why would you wish it to be stackable?
A. I don't know. Maybe when you run out of bog roll, you may want to pile some other Gridfinity items on top temporarily. Or you could use it as a little tray. As a general principle it's nice to design things with flexible use cases.

Q. Why would you wish to access bog roll with one hand?
A. The answer is beyond the scope of this post.

Q. Which version should you choose?
A. This primarily depends on your use case. Do you need to access bog roll with one hand? Do you like to GRAB or STACK? Do you prefer to have a reusable tray that will future-proof you against the possibility that you may not need bog roll in your bedside table at all? It's a really difficult question, I have personally struggled with it. So many things to consider. As to whether you choose the blue pill or the red pill, that's totally up to you. Just make sure you think about the choice very carefully. Maybe sleep on it, come back to it the next day?

Q. Printing Tips? (OK I'm being serious now.)
A. Glad you asked. YES - this applies to all Gridfinity designs! Set your bridging angle in Prusa to 45. This prevents very long bridges that definitely cause droopy plastic, which will definitely cause your 2x2 or more part to rock on the base. For some reason nobody seems to notice this but Prusa Slicer doesn't adjust bridging angles on the same Z plane so that they always take the shortest path. If you want to see what I mean, after slicing, use the up-down slider to go to the first layer after the bottom Gridfinity squares, the one that bridges the whole part together, and check to see if all the bridges between the squares are the same direction. If they are, then you need to do this!
