UPDATE: Since it seems that Printables is having trouble showing the “download all files” button (maybe I broke something, ups!), I've added six zip files at the “Other files” section (bottom), with all the files split in 3 parts per slot size (3 zips for 0.25mm slot, 3 zips for 1.5mm slot).
Here's a very extensive set of standees or holders for cards, 2D printed minis, tokens and even desktop notes —which is useful, as you can pass your DIY minis as “office supplies”.
The variants are as follows:
Note that the clip shape allows the insert to “lean” a bit if there is some room for wiggling; that is, you don't need to fit the exact measurements. Also, paper (and cardboard, cardstock…) has much give, so you can fit more than one sheet in the thin slot. Long story short, the two slot sizes can work for more things than one would think at first.
As you see, basic size is 25mm metric (not the 25.4mm of an inch) and each stand has a “clutch” or clearance of 0.1mm by side; this will help you see the grid and have large arrays or armies withouth having to worry about overstepping on another square. So, for instance, a Gargantuan side will be 99.8mm (instead of 100 or 101.6).
Colossal is some kind of oddity. First, is a Pathfinder-only size (which would be 30ft. side, or 6 squares), and second, the hex grid footprint is not 6, but 5 hexes (or 25ft, not 30); so we consider it to be 125 and not 150mm of side; but feel free to scale X and Y by 120% if you really need a 150mm token holder (which may be more of a pizza plate and less of a holder, but anyway…). This “small Colossal” may work nicely with some of the biggest Gargantuan-sized paper miniatures, just as Huge is sometimes a better fit than Large (we didn't get really rid of “tall” and “wide” large/huge, after all…). YMMV, but you have options.
Sizes for even-sided n-gons are measured by the distance “from flat to flat” (apothem x 2), whilst for the odd-sided n-gons are measured by their greatest width (and thus protrude from the facing vertex, whilst even-sided protrude from the flank vertices). Slot orientation is placed taking into account the “facing” rules in SRD when possible. The “rounded” versions of the n-gons fit in the same footprint as the non-rounded ones.
You might notice that the Tiny size of certain variations of the narrower 2x1 shapes for 1.5mm slot are missing (beveled, incurved, stepped); there simply no is room for the prongs with the border removed.
The 0.25 slot may end up “clogged” on one side, due to seams/retractions/stringing/etc. If so, just pass gently the blade of a hobby knife through the slot with a saw-like motion; do not use your sturdy working knife, it will be too thick. The flex of the clip will depend, of course, on the material; use PLA if you want it mostly rigid, and PETG, PP or PVB well soaked in IPA after printing if you want more flexibility. Obviously, TPU will have the greater flex, but it may be too much.
You may also cut the clip if you just want some good ole miniature bases. Just so you know, the clips start at z=3.125mm, which may seem an odd measure, but is exactly 1/8 of the basic unit and also allows for a bit of flexibility when it comes to adaptive layer heights and z-based color changes. You might also cut the clip, separate it into parts and move them if you need another slot width not presented here, but this may be a bit trickier.
Clips are 8mm tall in total, 5 mm to the narrowest part and 3mm over it; the bottom part of the clip is slightly over 5mm long (about like 5.6), so you can use it to add 5mm labels.
The paper minis seen in the pictures are from Printable Heroes. They do not sponsor nor endorse these stands, but they do indeed offer a great variety of models —many of them for free. They do also have several, very affordable Patreon tiers —I suggest to check them out!
