Designing and 3D Printing 15mm Fantasy Bases and Movement Trays

I have been loving Tinkercad and I needed a solution for my 15mm Fantasy basing woes.  I have designed a prototype that I think I am going to stick with.  I haven't glued the figures to their bases yet but will most likely go ahead with this prototype and it will be the standard for my 15mm basing.

I predominantly want to do 15mm Fantasy for dungeon crawling however I do like the idea of using them in other systems and they look awesome in Rank and File.

The prototype in its full glory! Pretty stocked with this!

First off I designed a base in Tinkercad that would accommodate a Ral Partha figure and a 1mm magnet.  The Ral Partha troops are around 10mm in diameter with their included base.  The figure will "sink" into the base with room for a 1mm magnet underneath it. The dimensions of the base are 12mm x 12mm x 2mm.  The 10mm hole for the figure is 1mm deep and the hole for the 2mm x 1mm magnet is 1mm deep.

I then printed it off and everything came out nicely.  My printer does need a little fine tuning.

I used a zombie to test it, worked out very nicely

I then needed to design a movement tray.  I am completely unfamiliar with massed battles and movement tray sizes for 15mm. I wanted to start off with a 4 x 2 tray and came up with the following.

The prototype movement tray

The dimensions for the tray are: 51.5mm x 25.9mm x 3mm.  This will allow the figure on its base to fit nice and flush and allow a 2mm x 1mm magnet to drop int.  The walls dividing the figures are 0.3mm in width!

I did a test print which came out well except I need to tune my printer slightly.

Needed a little clean up but design checks out!
I made the holes for the magnets slightly bigger than 2mm to allow a little extra room however I found I don't need it as I tweaked with my slicer settings.

The magnets were slightly loose but this will be an easy fix in Tinkercad.  They were glued in.

I was pretty impressed how this turned out.  I decided to put my skeletons into the bases and everything checked out!

They fit nicely and provide great stability for my 3D printed dungeon

Rank and file looks awesome

12mm x 12mm base size feels just about right

What's next?

Once I get some feedback from the internet I will adjust the design and go from there.  I am already thinking the 12mm base is almost perfect in size, as it provides great stability and isn't too big.  Any smaller probably wouldn't work.  I need to tighten up the holes for the magnets as my slicer and 3D printer are super accurate!  I am not limited to 4 x 2, any combination is possible.  I just need to improve my skills in Tinkercad to churn out the movement trays.

Once I am happy with everything these will be released on thingiverse.
