Multiboard Gridfinity Drawer Chest 5x3 Remix with Multiconnect

Introduction

I wanted a way to add drawers to Multiboard. Initially, I adapted the 5x3 shelf unit by David D, but then I figured, why not build his Multiconnect mount system into the drawer chest unit?
 

Mounting to Multiboard 

The instructions for mounting to the Multiboard are the same as for the shelf. You need at least one Multiboard connector, but you may use as many as you like. Connect those to the Multiboard, then slide the chest unit over all the connectors. The bin should “click” in when pushed down.

Stacking

Use the Gridfinity grid on top and bottom to stack. If you print the version without a Gridfinity base (see “Printing without Supports”), you can still stack the original Gridfinity Drawer Chest Remix by @rhencullen. 

I'm not sure how much weight they will bear - or how high you can stack - but David D's connector looks extremely solid. 

One important advantage of the full-fat (grid top and bottom) version is that you can add Multiboard mounts to the stacked units. Holding the stacked units to Multiboard makes it much stronger, and you can stack as high as you like.

With both designs, you can use the grid to add other gridfinity modules to the topmost unit. Go crazy!

Printing without Supports

There are two versions.

Tested on Bambu P1S, the version without the Gridfinity base didn't need any supports, used less material, and printed faster. A small chamfer on the bottom edge ensures good baseplate adhesion using the brim alone.

(If printing with just the brim doesn't work for your printer, you could always print it with this stand.)

The version with a Gridfinity base requires supports, but they are very easy to remove, given the 45º angle.

I had to scale the chest up very slightly (by 0.7%) in the Z direction to ensure the drawers' free movement. Without the upscale, the drawers would stick when the model was printed at 45º. 

I printed in PETG and PLA.

Drawers

As with rhencullen's original remix, use the original drawers from Blasterdad's project.

OnShape Project - Exporting STEP

Note this is the first remix I have ever made - one of the first things I ever modeled. So, I couldn't work out how to export a STEP file - only STL seems to work.

The OnShape project is here.

If you know and can tell me how to export a STEP file that includes the original chest, that'd be wonderful! (When I export, I only ever seem to get the mount and stand, not the chest.)
