3D Printing Data for a DB-01

Should I read this page?

In short: if you buy a finished DB-01 from me, then no. If you want to print parts of your DB-01 yourself, you should check the following page.

This page is the central point where you can find all necessary or additional printed (spare) parts. If I develop a new part, adapt an existing one or receive a user submission, you can find it here. Of course including required information.

Explanations about the 3D printing data

Below you will find all the data you need for your 3D program / 3D printer (as soon as I have completed the prototype). Just download and import a .stl into your slicing program to get the .gcode for your 3D printer. I use Ultimaker Cura for slicing.

All parts are no larger than 210mm x 210mm x 210mm. So most 3D printers can print them. At the moment I personally use a slightly modified Ender 3 printer – nothing special. Common 1.75mm filament, a 0.4 mm nozzle and 0.2mm layer height. I usually print with 40% infill. When I construct things and quickly need a physical draft, I print at 20%.

I like to print with a skirt. Simply to have a regular filament flow and visual control of the print bed distance. If the distance is too low, for whatever reason, I have no problem lowering the print bed manually with a tweezer and some pressure for the first layer (not the greasy fingers!).

When i have problems with warping parts, i prefer to use a brim before i mess with other values like bed or nozzle temperature.

But before we go to deep into details here, i recommend you reading the page “Tips and tricks for assembling a DB-01“. There i also give a lot of tips and share my experience with printing a DB-01.

The table columns “Time”, “Weight” in gram and “Length” in meter refer to theoretical values from Cura according to my printer settings. In practice, my printer is a little faster. I practically print p024v002 in 17 hours and 13 minutes, instead of the 18:55 calculated by Cura. You will probably have different values with your printer. These 3 values only serve as a rough guide.

I understand that if you’ve never built a DB-01, you don’t necessarily immediately understand which part is where, what it’s needed for, or whether you need it at all. That is why I offer additional help pages. Just click on the description of a part to get further explanations. Also good to know: almost all parts (except the very small ones) have the corresponding part number stamped on the component.

db01v001p001

This middle plate for attaching up to 12 L298N has a groove like all middle plates. When slicing the model, turn on support, but increase the threshold to 55 degrees. The maximum angle within the model is 45 degrees. So you have practically nowhere support. However, this setting guarantees you the effective non-use of the support function.

The model is 214 millimeters long and 214 millimeters wide. Normally a commercially available 3D printer should have no problems with this. However, you absolutely need a level print bed. A glass bed serves me well.

db01v001p003

The parts of the p003 series are spacers. Mostly to keep electronic components at a distance.

p003 is available (in addition to the obsolete / grayed out versions) in several versions. For example p004v002, p004v003, … The different versions have different dimensions. This means that you have a spacer for every situation.

db01v001p004

The parts of the p004 series are spacers. They wrap around the threaded rods / screws that hold the middle plates together.

p004 is available (in addition to the obsolete / grayed out versions) in several versions. For example p004v002, p004v003, … The different versions have different lengths. This means that you can regulate the distance between the middle plates as required (determined by the height of the built-up parts).

This part is not essential. It is only the covering of the antenna box. The antennas themselves are held by part p013. p014 is also the holder for other accessories such as the ESP32 for the WiFi connection. Must be printed with support. If you do so, the three big cable holes in the walls are more or less closed and you do not need aditional covering for them, if you don’t like to print additional coverings. If you want to attach additional component boxes for e.g. an ESP32 to p014, you have to press out this support structure after printing.

db01v001p017

This part connects the second leg motor with 3 threaded rods. The part also serves as the first end cap of p023. p017 and p023 interlock using a tongue and groove system.

I print the part without a brim or a raft. Warping should be avoided by the special design. If you experience warping, first change the filament settings. The use of a brim also avoids warping, but has always covered up the groove, which I then had to clean manually. Ugly.

I print the part without support. The 8mm hole should print your printer correctly. At least mine does. If it gets slightly unclean with you, don’t worry: the hole will not be stressed. Or just print with support – but whether the hole will be more beautiful?

db01v001p019

This is the first part of the second leg element. It connects motor 3 on one side and 3 threaded rods and the leg cover 2 (p024) on the other. So this part also serves as the first end cap of p024. p019 and p024 interlock using a tongue and groove system.

I print the part with support, beginning at 60 degree (like p021). And i say “Just touch buildplate”. With this i have a free notch and the 4 holders for the (wide) motor 3 metal bracket are supported during printing at the crucial points.

db01v001p021

Parts p017 to p022 have a tongue and groove system with their corresponding middle tubes p023, p024 and p025. So your printer should not print an elephant foot that is too pronounced or tend to warping. For this part, I only print without brim and support starting from 60 degrees to keep the groove free. If your printer is not able to print properly, you have to choose a higher level of support and clean the groove from the support construct with a craft knife. A brim (or other printer / filament regulations) will avoid warping.

Parts p023, p024 and p025 have a tongue and groove system with their corresponding end caps p017 to p022. So your printer should not print an elephant foot that is too pronounced or tend to warping. If you have problems with warping, print the part with a brim. Printing with support shouldn’t be necessary. Your printer should print the holes and 45 degree overhang without grumbling. If you print with support, you have a little more rework on the groove and the printing time / material requirement for this part increases considerably.

With 132.4mm this part is relatively high. Therefore, your 3D printer should not have too great a deviation on the vertical axis. To test or calibrate this, you can print a common calibration cube and regulate your printer accordingly.
