Magnet holders for tool board

I've used magnets to hold some of the tools on to my tool boards in the workshop. They have a tendency to slide about when removing tools.


To keep the magnets where I want them, I've designed and printed some simple holders that fit the Bott tool boards that I use.

My first resin 3D printer

My Christmas present to myself is a HeyGears Ultracraft Reflex 3D printer.


The Cure unit arrived first, then the resin and just before the New Year, the printer arrived.






Setup and getting it going was fairly easy. It had 8 setup screens to go through. It included levelling and updating the firmware, among a few other things.



My test print was a scaled down Millennium Falcon model. I printed it horizontal, for speed, but that meant there were a lot of support marks on the underside. The top surface showed the quality that the printer could produce. 



The post processing was not as fiddly or time consuming as I had expected. I used my existing ultrasonic cleaner to wash off the uncured resin. I'd seen a tip on a YouTube video to put the isopropyl alcohol (IPA) in a plastic bag. This avoids the chance that the IPA could degrade any rubber seals that may be in the unit and it also reduces the amount of IPA that needs to be used.



I filled the ultrasonic cleaner with water and put the bag of IPA with the print inside, into the water. I ran the unit for 10 minutes, which did a good job.




I removed the supports and quickly dried the print before putting it in the curing unit for 20 mins.
