In experimenting with mounting an endoscope camera on the rear of the MK3 extruder, I found the endoscope was crashing into the Prusa heat-bed cable cover assembly during mesh bed leveling. The Prusa cover height appears to be 5mm, with…
This is a remix of the LMU Bearing Grease Packer with a nut on the end to firmly hold the bearing while packing it with grease. While I liked the design, I had some frustration with the 4mm thread, finally cross-threading it. I copied the…
The Big Einsy case is an awesome concept. This remix addresses the issue of being able to easily access the frame fixing screws, especially after assembly. A channel against the frame has been opened up to route a +5V power cable up to a…
The Delta-P Duct is an awesome concept. While there are already designs for fitting an endoscope camera, I wanted a system where the camera could be easily removed without disturbing the extruder cooling and restore the excellent view of…
Update 18 Nov 2023 I recommend no longer using this rear camera arrangement. After some use I was a bit heavy-handed with the locking screw and damaged an endoscope camera. I would not like that to happen again. Also, I have always found…
The cap is hown here on my MMU3 / MMU2S MK3S+ PC4-M10 Extruder Anti-Twist Screw-Adjustable IR Sensor Adapter. https://www.printables.com/model/650466-mmu3-mmu2s-mk3s-pc4-m10-extruder-anti-twist-screw- To be able to see the LED state, the…
Update - V2 One of the expected benefits of this approach, from keeping the fan on the outside of the case, should be the life of the fan. Only the impeller is constantly subjected to the set 70°C. The electronics in the fan should be at…
Both the puller body and the thumb-wheel use a standard M3x6mm hex spacer rather than just an M3 nut, which might deform under pressure. Two M3 mudguard or nylon washers improve operation smoothness, transferring the pressure to a larger…
I wanted to mount an PRi4B at the top of the MK3 frame to enable a nozzle camera. I fitted the large RPi4B heat-sink to ensure no heat issues. The design is meant to minimize any air flow restriction. The RPi4B frame mount has multiple…
I'd become bored with measuring the weight of espresso coffee beans on each shot. So I adjusted the size of a cylindrical measure to hold the number of beans that matched the 17g shot I'm used to making. The shape of the measure is to…
