Total hours: 47

BOM: https://docs.google.com/spreadsheets/d/1BoM7iUl6QUpEB06v-WNWhYhMciubwFNZ1HohTmLiy30/edit?usp=sharing

2/13/25 - 2 hr (2 total) Started Project, began researching basics on 3D printers, watched Youtube videos and builds

2/14/25 - 1 hr (3 total) Continued basic research, began thinking about design requirements, studied other DIY 3D printers

2/15/25 - 3 hr (6 total) Watched more YT videos on 3D printers, researched and created BOM for toolhead, began importing models to CAD. Time was spread out throughout the day

2/16/25 - 3 hr (9 total) Finished draft of BOM, began cadding mounts etc to connect everything together (spent an hour trying to find a 3d model of carto. probe to no avail)

2/17/25 - 2 hr (11 total) Continued working on toolhead, began thinking about frame and movement system https://cdn.hackclubber.dev/slackcdn/6684845de0eb26d4113f0da41a8cba38.png

2/18/25 - 1hr 30m (12.5 total) Researched and worked on frame design. Spent wayyy to long creating a linear rail model.

2/19/25 - 30m (13 total) Attached toolhead to rail, did some more research

2/21/25 - 1hr (14 total) Finished toolhead

2/23/25 - 2hr 30m (16.5 total) Struggled to download and use autodesk cdf. When I finally began running simulations, they were all completely goofed. Notably:

3/4/25 - 1hr 30m (18 total) Settled on frame designl, bedslinger. Began working on X axis mount and belt drive.

3/8/25 - 2hr 30m (20.5 total) Locked in on CFD, created first two iterations of my first design, a 2 stream blower funnel. V1: V2: Both completely missed the nozzle end ._.

3/9/25 - 3hr (23.5 total) Finished second version of the double funnel, promising first results Finished the frame and brackets for all 3 axis. The printer’s really starting to come together.

3/10/25 - 1hr (24.5 total) Began researching for beds and electronics Finished X and Z movement systems (specifically belt mounts) Build volume is currently looking to be around 19 x 25 x 16 (xyz), which I’ll definitely have to look into tomorrow. One way is to cut down the Y axis by 5, which brings the volume to a fairly square 19x20x16

3/11/25 - 30m (25 total) Did some random small work. Here’s the current build volume roughly visualized (24x24x18)

3/14/25 - 2hr 30m (27.5 total) Finished up (almost) all of the 3D printer not including electronics

3/15/25 - 1hr 30m (29 total) Started the day with minimal knowledge on 3d printer electronics setups, ended with a solid grasp of components and how they work together.

3/16/25 - 5hr (34 total) Finished researching electronics and finalized parts needed. Went through the BOM and checked and counted up everything. The costs seemed to shoot up significantly after I actually tallied everything up, going from my expectation of ~250 to 350. I spent a lot of time switching and cutting parts to get this number down. One of which was replacing the cartographer probe with a BL Touch clone. Here’s the full printer rendered (ooh).

3/18/25 - 2hr (36 total) Spent some time looking over the the BOM again. After trying to find cheaper alternatives for every part, I got the total down to around 330 total before tax. At this point, I had submitted for the grant and bought all the parts.

3/19-3/24 - 6hr (42 total) Time was scattered throughout this period. By the end I had mostly finished redesigning the printer. (Ignore the glaring issues with bed movement, will figure it out next time)

3/25 - 30m (42.5 total) Continued redesign

3/26-3/28 - 2hr (44.5 total) Fleshed out redesign and made some really cool renders. Check out renders tab!

4/2/25 - 2hr 30m (47 total) Finalized the redesign, made all the parts look nice with chamfers and fillets. Most of the parts have arrived, but still waiting on a few.
