Repo Finished!

I made my readme and added all the files. William helped me with my renders! I also sanity checked it again to make sure everything is perfectly functional, and it is!

FINISHED THE PRINTER

I finished the feet, assembled everything in an actual assembly, fixed some design issues, recolored, added feet for the motors, and yeah everything's finished yay

I also made my BOM

PSU

https://www.aliexpress.us/item/3256805101944097.html? Fan = https://www.amazon.com/Wathai-Brushless-Cooling-Centrifugal-Airflow/dp/B07RMJC9NT/ is the cheapest I can find from ali or amazon 12.3 watts * 2
2.1 A

48 mm nema 17 = https://www.aliexpress.us/item/3256801583088255.html $41.52. According to https://www.tinytronics.nl/product_files/004446_17HS8401_stepper_motor.pdf, thats 1.7 A, 1.7*4A = 6.8 A

Heatbed = https://www.aliexpress.us/item/3256801715397979.html, 20.33. 60W +/8 percnt =65 watt, 5.5 A

rpi 02w research voltage source: https://www.seeedstudio.com/blog/2025/12/01/raspberry-pi-power-supply-guide/#:~:text=Table_title:%20Comparison%20Table:%20Raspberry%20Pi%20Power%20Supply,Recommended%20Solution:%20Standard%201.2A%20Micro%2DUSB%20supply%20%7C

5V×3A=15W, 15W/(12V×0.85)≈1.5A

LM2596 seems to be a really good and cheap buck converter. https://www.aliexpress.us/item/3256808348795887.html?

btt wont be much either, so adding them up with some headroom

Made wiring diagram + feet

make assembly and make ducts, fixed minor uisues

1. I revizsed the plate dimensions and redid the bed (although it looks similar, dimensions a4re different)
2. I added ducts for sheetcooling
3. I crosschecked the design!

https://www.aliexpress.us/item/3256809710345126.html

Add bed assembly and polish up top n bottom!

I added the bed assembly.

to do this, I calculated the distance from extrusion to lead, I then made the assembly for the linear rails and lead screw, calculated that 150 indeed is good, and put that in

Made Lower Bracket (yesterday)

lower bracket

NOO I should put it on the bottom

OK so I changed from triple z to dual z with the nuace that removing prints will be hell, but I think its good for budget

frame size

210653.825485 mm^3 being extruded out a 4.44747 diam = abt 14 meters. Id say 2.0 mm ish per layer is reasonable?

ANYWAY

158.84518-35.00000 = at least 125 mm even with no z length. Lets just make it a square gantry :) thats 250 again,

gooahh

ok I did a shit ton of research and thinking, im going to do smth similar to a trident except add something like from the Monolith 0 to the bottom. My BOM should prob be really low :huzzah

I made some of the frame and ya

I made the other 2 mounts kinda, they drafted

I made a rough sketch (attached)
I also have the toolhead (attached, im going to add 5015 cooling
For the bed, my plan is to make a bed that I can add a thin sheet of aluminim to or something similar

I also modified my toolhead

added support so its now supporioted in 3 places, and the top part is more stable.

ok nvm

since it goes out, it would intersect anyway. Im going to stick with 2040 to have 2 rails then. that sucks noooooooooooooooooooooooooooooooooo well yes but no its less polished but now less cad work idek dude

I made the x gantry mounts

Ill add a self-threading m3 hole here

like I said before, I need 2040 here bc the toolhead is gigantic,

GAHHHH N0OOOO I CAN MAKE IT A 2020 AND JUST HAVE THE OTHER ONE ON TOP WHAT AM I DOING

THEY INTERSECT ANYWAY

Basic Gantry work

so I did a bunch of thinking on the gantry

for stabilization, x gotta be dual mgn12 so im doing 2040 vertical, looks ugly but it is what it is

attached is the belt path!

Created toolhead

Im making a toolhead that can connect to lin rails

to make sure its acc 150 ML, 42.60000 mm d 147.79518 height mm, (42.6/2)^2pi147.79518 mm^3 => ml = 210653.825485 mm^3, 1ml = 1000mm^3, 210.653825485 ml is good yayy

https://www.aliexpress.us/item/2255800576028509.html 100 mm rails are good with MGN12

The main goal of making this so tiny is to print everythign on my ender 3 LOL

1.17336 center distance

https://www.aliexpress.us/item/3256802773736204.html for lead screw, ill do 150

nvm I use https://www.aliexpress.us/item/3256805576723890.html

due to screw issues, I decided to make this toolhead attachement

I added a wall so the toolhead dont slide off

https://www.aliexpress.us/item/2255799990666860.html coupler

width of my toolhead = 65.36452+150= I need a 220 rail

YAY I finish toolhead, only took me 5 hours

TLDR:

Based off the tube I made the plunger:

based off that I made the outer gantry

and thats done!

research

so I want a corexy or smth with a stationary build plate

I was looking into PCBs and heated beds and whatnot, WAIT A SECOND I DONT NEED ONE!!! THIS IS ICING LMAOOO

icing seems to cool fast ash when constant cooling is applied

ok so this is the plan

Im going to make a 3dp with a 120x120 bed thats corexy. I dont entirely think levelign is needed but for polish ill add it bc why not, if I have time. since its a corexy, sheetcooling shouldnt be hard. ill have 2 5015 on the toolhead. toolhead will also be a syringe, driven by rack and pinion or whatever was in this video, it lowk seems more polished to me.

https://www.youtube.com/watch?v=Ui0dcF48U9k seems like a valid proof of concept, and with a corexy, this should be better.

https://www.thingiverse.com/thing:3487917, ill either be basing toolhead off of this or rack and pinion.

I think ill do 150 ml, a solid 3x3 cube seems like its good!

Ill be working on my toolhead now, see u there :)
