16	Sourcing status	Mounting status	Comment	Printed parts	Qty per printer	Comment
17				layout_a4.pdf	1	This is a 2d printed part. Letter-sized pdf can be made with `make layout_letter.pdf` in the repo.
18				1XD_holder.stl	4
19				bearing_u_608.stl	1	Fit these around your 608 bearings
20				bearing_u_big_623.stl	40	Fit these around your 623 bearings
21				belt_roller_insert.stl	4
22				brace_tightener.stl	3	For attaching corner clamp to nozzle via metal wire
23				corner_clamp.stl	3	This one isn't CAD done yet. Expect changes
24				dleft_spool.stl	1	A bigger spool that can hold two of the three D lines
25				dleft_spool_cover.stl	1	Keeps line from falling off of D left spool
26				dright_spool_top.stl	1
27				dright_spool_bottom.stl	1
28				dright_spool_cover.stl	1
29				extruder_holder.stl	1	May get hot. Use heat resistant plastic
30				GT2_spool_gear.stl	4	This one can be tricky to print. Wrap your belt around, and scale up/down until teeth match all way round. There's also a flatness requirement. Keep warp at minimum by disabling cooling and printing slow.
31				horizontal_line_deflector.stl	4	Used for guiding lines around internally on the ceiling unit
32				landing_brackets.stl	1	Note that the stl contains all three landing brackets
33				line_roller_anchor.stl	6	Also called "foot block" and "Snaily Snail". Line should enter the bearing as straightly as possible. Look at half tilt and straight versions if they match the line angles of your setup better.
34				line_roller_anchor_template.stl	1	Used for placing out screws below line roller anchor.
35				line_roller_wire_rewinder.stl	1
36				line_verticalizer.stl	3	Used for guiding D-lines off of ceiling unit
37				motor_bracket_A.stl	1	May get hot. Use heat resistant plastic
38				motor_bracket_B.stl	1	Also hot
39				motor_bracket_C.stl	1	Also hot
40				motor_bracket_D.stl	1	Also hot
41				pi_mount.stl	4	Spacers to help mount raspberry. They are longer than the ODrive's and the Duet's spacers, so HDMI port stays unblocked
42				sep_disc.stl	1	Used to divide the D Left Spool into two separate sections
43				spool.stl	6	There's a flatness requirement. If tiny bit of warp: Find high points along edges. Mount symmetrically: Push high points of the two spools together into GT2 spool gear. Found to reduce wobble.
44				spool_cover.stl	3	There's also a squareness requirement on your printer. If any of spool or cover diameters are off my more than 0.25 mm, then you will get problems with spool edge rubbing on inside of spool cover.
45				spool_cover_mirrored.stl	3
46				new_tilted_line_deflector.stl	3	Used for guiding A, B and C lines off of the ceiling unit
47				Picam/Arducam mount	1	This is a bit half-done, since I've taped a 40 mm fan to my lens_holder_arducam. Get here: https://gitlab.com/tobben/hp-mark/-/tree/master/picam-mount. See https://twitter.com/tobbelobb/status/1377240814724730881
48				hp-mark-markers/retroreflective_plate.stl	6	Cover flattest side with retro reflective tape. Cut to make edge perfectly circular.
49				hp-mark-markers/contrast_edge.stl	6	Print in black.
50				hp-mark-markers/marker_slider.stl	6	Used for mounting markers to beams of effector.

53				Vitamins	Qty per printer	Comment	Example part	Ebay/Amazon search example	Cost	Source
54				Nema17 stepper	1	For extruder if you're building a 3d printer (some Hangprinters are solely used for pen-plotting).	ebay	Nema17 Stepper Motor 40Ncm
55				Line: DC Pro 161, thickness 0.83 mm	100 - 150 m ?	Calculate how much line you need, and buy extra so you have backup. Also used for connecting corner_clamp.stl to pen_fly_brace.stl if you're making a pen plotter.	liros.com
56				MDF or plywood sheet	50x60 cm	Thickness 10-14 mm
57				MDF or plywood sheet	50x10 cm	Thickness 10-14 mm. For building anchors. Bolt these to the floor.
58				Duet3	1		duet3d.com
59				1XD expansion board	4		duet3d.com
60				RJ 11 (6P4C) connectors and cable	4	At least 8 connectors. I've made very short ones, and drawn out 2 wires for ODrives who have separate CAN, see tweet -->	twitter.com
61				ODrive v3.6	2	Match voltage with the output of your power supply. I use 24 V. Warning: Chip supply shortage is pushing this alternative out of the market. Support for ODrive Pro and S1 boards is on Hangprinter's roadmap.	odriverobotics.com
62				USB isolator	1	Use between your laptop and the ODrive.	odriverobotics.com	USB isolator
63				Power supply	1	24 V, 25 A or higher recommended
64				Raspberry Pi 4, at least 2 GiB	1	Separate power supply needed. SD card included with the Duet3. Otherwise buy separately.
65				Raspberry Pi official power supply	1
66				BLDC motors	4	Dual shaft motor D5212s/D5312s 300kv/330kv. Printed parts are designed for exactly this motor ---->	odriverobotics.com
67				Encoder for BLDC	4	CUI AMT102-V 8192 CPR encoder. Printed parts are designed for exactly this encoder.	odriverobotics.com
68				Bltouch	1	This is a bit optional but will improve the user experience and make it easier to print big first layers
69				40 cm rectangular/square beams	3	Widths from 12.5 mm to 17.5 mm supported, 15 mm recommended	hobbyking.com	15x15x500mm Carbon Fiber Square Tube
70				27.5 cm rectangular/square beam	1		hobbyking.com	15x15x500mm Carbon Fiber Square Tube
71				GT2 Belt loops	4	610 mm long, 6 mm wide
72				GT2 Motor gear	4	I use 20 teeth for now. For a lighter, faster tool head, consider using more teeth. The recommended motor from ODrive has a 5 mm shaft, so get a 5 mm bore.
73				Smooth rod, 8 mm diameter	ca 30 cm	To hold spools. Cut in pieces: 3x62 mm and 1x80 mm.
74				Retro reflective tape	1 roll	For hp-mark's markers
75				Long flat 15-pin cable for hp-mark cam	ca 3 m?	How long you need depends on how far from Pi you mount your cam. Aim for 30-45 degree angle towards origin.
76				LED ring 12 LEDS	1	See https://twitter.com/tobbelobb/status/1377240814724730881
77				LED ring 8 LEDS	1	It's not important to have exactly this setup. How to control/wire up LEDs is not completely determined.
78				Extruder + hot end	1	Use some high-flow system. The extruder mount has Nema17 screw holes prepared.
79				40 mm fan	1	To cool the hp-mark camera
80				Arducam IXM 219	1	I've used this one because lo-dist lens can be mounted, and sensor is same as picam v2.	arducam.com
81				Arducam low distortion lens kit	1	I use the narrowes FOV one in the kit (45 deg). I think it could be bought separately as well.	arducam.com
82				Hex head M3 screws. A few mm long. (5mm?)	6	Used for fastening markers to marker sliders.
83				M8 screws, flat head, 22-30 mm long	12	For ABC line guides	amazon.com
84				M8 nuts	12
85				M3 screws & nuts	999999999	Shortest: 5 mm. 16 pcs. Longest: 40 mm. 4 pcs
86				M3 nyloc nuts	at least 8	Used in belt tensioning mechanism
87				Embroidery machine eyelets	42	Used along line paths. KP-SS-B-150	amazon.com
88				Double sided tape	1 roll	Put between printed part and square beam when assembling effector triangle
89				Metal wire ca 40 cm	3	For connecting effector corners to nozzle if you're building a 3d printer. I've used guitar strings on my prototype.
90				Zipties	18	Widths 4 to 5 mm recommended
91				608 bearings	9		kugellager-express.de
92				Flanged 623 bearings	8	For belt roller. Belt idler with 3 mm bore for 6 mm belt might also work well but haven't tried it myself yet.	kugellager-express.de
93				623 bearings	40	Try to find ones that don't rattle	kugellager-express.de	thebearingstore.com
94				Ferrite rings	4	One for each ODrive motor. See https://odriverobotics.com/shop/n97xgxel6y0ufvunsxq70kih4p19nx for how to use them.	odriverobotics.com
95				Red and black power cable	ca 3 m	For connecting 24 V to Duet, ODrives
96				15-lead ribbon wire	5 m	Or 30-lead 28AWF with quadrupled wires to/from the heater element.	ebay	30 Way Flat Ribbon Cable Wire 28 AWG
97				14-16 AWG 200 degree cable	ca 3 m	For connecting BLDCs to ODrives. Not needed if you ordered these: https://odriverobotics.com/shop/dual-shaft-motor-d5212s-300kv since they ship with 400 mm wire length.
98				Nice connectors	12	For connecting BLCD wires to ODrives
99				M3 self tapping wood screws, length 12 mm	ca 100	The 12 mm length is not crucial, but use as long as you can without going through your wooden sheet. Not countersunk, as that risks splitting platic parts.
100				Plank, ca 4 x ca 11 x ca 50 cm	2	Bolt these to your ceiling. Then attach ceiling unit (wooden sheet) to them.
