u/Dry_Armadillo_Humper

Designed in Shapr3D, printed in Ambrosia “Coral Wave” ASA. Holds two 3kg spools, or a single 5 or 10kg spool.

No roller bearings — so no overshoot, and no tangles, which every other roller I’ve tried causes with large spools. It also handles bigger spools than most, and happily feeds 2× 3kg spools to two different printers simultaneously.

Runs on a 5/16”ø × 12” hardened steel rod with an optional PTFE sleeve. End caps slide over the rod so a tangle can’t pull it up and out, and printed collets keep the spools from walking laterally on the spindle. Best roller I have ever used.

I have just over 3K hours each on my H2S and H2D. Aside from regular lubrication, filter and filament cutter changes, I have had the following issues and I am wondering if anyone else has seen these issues and if so, at what point?

H2D:
- worn extruder gears needed to be replaced (2k hours)
- left hotend heater unit died (3k hours)
- USB port died (1.5k hours)
- Extruder motor on last legs, needs to be replaced
-PTFE tubes replaced (2k hours)

H2S:
- filament sensor cable broke at about 500 hours, replacement had much longer cable.
- heatbed alignment tabs broke off (2k hours)
- Extruder gears worn at 2k hours
- cable chain snapped mid print causing the PTFE tube to get stuck in the cutting blade pusher, that ripped out the filament sensor, thermistor wires, and USB cable (2.5k hours)

Aside from the catastrophic failure of the cable chain this all seems pretty reasonable given the duty cycle I run, so I am not complaining. Just curious what others have seen.

First off; yes, I know I could but a cheaper hammer. That’s not the point at all 😂

Handle is Lyten PA1205, head is Sunlu PC-ABS. Metal disk is from McMaster-Carr. The metal striking face can be walked out and replaced or flipped over by tapping a hex key into the two holes on either side. Handle is press-fit into the grip and the head is with added Lyten adhesive for extra security.

One side for tapping together my press/interference fit parts, the other side for occasionally hitting a nail or other surface harder than plastic. I use this in my shop every day.

Printed in ABS. I know there is some banding between the rows of circles and some of the overhangs are a little bit rough (this was printed without supports), so it’s not a customer-quality print, but it does exactly what I needed it to (it fits where I need it and it provides plenty to f ventilation) and I actually think the banding effect looks kinda cool. Its small-ish for a laundry basket but large for a one-piece print 😅

We have three young kittens and a lot of original art. Rather than pay a gallery $3000 per painting to install plexiglass over them I designed and printed these brackets from Polylite PC and bought plexiglass sheets for $100 each at a big box store. Each bracket is designed to take 3x #8 wood screws. I drilled the center hole of each load bearing bracket into a stud. The side brackets are just to hold the plexiglass and do not bear any load.
