Stacking Feet for Snapmaker U1 for DOUBLE CC3D DRWR stacking

Stacking Feet for CC3D DRWR for Snapmaker U1 to DOUBLE STACK

This project includes a set of four stacking feet designed to securely locate and connect TWO (or more?) of Enrico’s CC3D DRWR modules beneath a Snapmaker U1.

The included print file is configured for TPU 95A. The feet may also be printed in PETG, although TPU should provide greater grip and vibration isolation. If printing in TPU95A on Snapmaker U1, you may need to tweak your settings for your print environment. To print in PETG (my tests were done in PETG), simply change the material to PETG and slice it - you'll have really thick walls and infill for PETG, but it's probably not worth the effort to change the file to save a foot of PETG and a few minutes. A generic PETG profile is also in the file as Filament #2

Required materials

Top and bottom of every foot should receive a thin adhesive layer:

• TPU95A or PETG
  I tested the file using both - but it is designed with infill and wall count for TPU95A to hold the weight without squishing - other than selecting the TPU or PETG filament in the file, no other parameter changes for EITHER material were used in my printing.

• Ultra-thin or thin 3M VHB

• Or an equivalent high-quality double-sided adhesive

Cut the adhesive slightly smaller than the circular mating surface so that no adhesive is exposed around the edge.

Installation

1. Clean all mating surfaces and allow them to dry completely.

2. Apply adhesive to both sides of each printed foot.

3. Remove the protective backing from the small side of the printed foot and press each foot into the circular recesses on top of the lower DRWR module.
   Doing it in this order will help ensure you can properly align the top DRWR with the bottom DRWR. 

4. Remove the protective backing from the exposed adhesive.

5. Carefully align the upper DRWR module above the lower one.

6. Lower it straight into position and press firmly so all four feet adhere evenly.

7. Verify that the modules are fully seated and stable before operating the printer.

The feet provide positive alignment between the two modules while the adhesive prevents shifting during printer movement.

This is for the Original DRWR Project fori U1

These feet are an independent accessory for Enrico’s DRWR system.

The original DRWR files and other Snapmaker U1 projects are available from CC3D Projects:

CC3D Snapmaker U1 Projects and DRWR

ALSO... Plate-Holder Feet

A separate print plate is also included with feet for the plate holder from jerryninov’s GridFinity Project for the Snapmaker U1:

Important

This is an independently designed community accessory. It is not affiliated with or endorsed by CC3D Projects, the original DRWR designer, jerryninov, MakerWorld, Snapmaker, or 3M.

Fit, adhesion, and material behavior may vary. Confirm that the completed stack is stable before operating the printer unattended.

Notes:

• File is built for Snapmaker U1 - adjust settings and plate (or convert) for other printers.

• Depending on your table stability and installation location, you may want to increase infill density and/or wall count before stacking – especially if you plan to stack more than two DRWR modules. This configuration has been tested only in my secured workshop on a stable steel table. Because your setup may differ, verify stability before use and stack at your own risk.

  • White is Tinmorry Light Grey (similar to/same as 3DJake Light Grey)

  • Orange is standard PETG Orange and matches all four brands I own lol.
