3D model description

This is an 8 container mechanical dice box (or pill box if you'd rather) that I have developed. It is a little tricky to print and requires some amount of either sanding or glue when assembling depending on how well tuned your printer is.

I have included two formats for the base piece, one with the pins for the containers to spin around and one without. If printing without the pins you will need to print 8 pins seperately and glue them in place. I did this as I have test printed this twice, and with the second one two of these pins snapped off, so having them seperate seemed beneficial.

To make this box you will need:
-1x Box_base OR 1x Box_base_without_pins & 8x Base_pin
-1x Box_top_prt_1
-1x Box_top_prt_2
-4x Compartment_4mm
-4x Compartment_19mm
-8x Con_rod
-1x Piston_base
-1x Piston_mid
-1x Piston_top
-1x Piston_wheel

If you follow through the images it will detail the assembly instruction, with it being assembled up-side-down. I'd recommend test fitting at each stage before you glue/press fit the pieces together. It is a little tricky to get everything perfect and may take a little bit of wearing in, but after a bit of use it opens and closes smoothly.

Great design, love it! I did find that the 8-pointed snowflake/gear binds on the connecting rods. I sanded each of the points to be rounded and it is working much better. I also found it easier to assemble from the bottom up.

Where do suggest gluing it up? It feels solid enough that it may only need it where the triangular posts connect to the top and the top ring.

Such great feedback, I really appreciate it! I could tighten up the tolerances on the con-rods and upload as a variant, I know from my printer it was a pretty tight fit but I get the feeling that blue PLA was a little oversized.

The print took ~15h total with Sidewinder X1 in PLA at 200C, 0.6 nozzle / 0.66 line width, 0.4 mm layer height and 60 mm/s speed. I used the entire build plate to fit as many elementss as possible.

Box_top_prt_2.stl should be printed with the triangle to the left of the bolt for a nicer finish.

The con rods could snap a little tighter, some disconnected a couple times when closing/opening the box.

I'll post some pics later.

Very nice project overall.

Hey man, so impressive that you've already printed and assembled one, I only listed it two days ago! Glad it all came togteher though, always a bit nervous with assemblies like this that they might not work on other printers.

When assembling make sure that the little triangles are positioned correctly (to the right of the bolts, like in the 5th picture) and that the element with cross (6th pic) has the holes up. Works nicely :-)

It will be nice to make an assembly video . TNX
