I tweaked the print settings in my slicer to fit my preferences. But otherwise, this assembles nicely, printed with PLA I'll probably do like others have an print 2 more bearings to minimize the clicking noise as it spins and the bearing drops. I also removed my spool holder when assembling to make it easier to get the bearings in the spool. Otherwise a solid design.

One of the best designs for simple whiteboard markers and eraser. I cut mine in the slicer for 8 markers instead of 12. Sits nicely on the desk, weighty enough to make for solid holder on the desk.

Solid. I've made several of these. Some materials (ie ABS) need to print high temp and slow speed to prevent them separating at the rim at the layer line. Also I bumped up my diameter by 0.5% (or 1%) to make it easier to fit on my Inland spools. I use the flat-edge version because the rounded edge interferes with my AMS.

As far as fit and design go, this one is top notch. Fits the Bambu damping feet (for X1C) perfectly. I like the actual slot that it has for the rubber foot to fit into, I feel that is more secure especially when this little guy (the A1 mini) is accelerating back and forth for fast PLA prints. Excellent model. Well done. If you're wanting to run this thing all night without the wife/kids noticing its running (aside from part fan noise), then this model will do the trick!

This prints waaaaaay nicer than the model photo. The design and fit is outstanding. I printed in Inland ABS in "Galaxy Black" at 260C in my Bambu X1C on PEI sheet washed with Dawn just before printing, chamber preheated to about 50C with the bedheater and aux fan running for 20 min. Add a 10mm brim for the tall part, the little parts don't need. And slow the print on the tall part waaay down. Max of 100mm/s (or 50mm if want to really avoid warping). I made mistake of printing faster around 200mm/s and she broke free 9mm from the end, giving a slight ridge. No Aux fan during print. Part cooling fan Min 10% with layer 30s, Max 30% with layer 12s. No cooling for first 5 layers. I had bed temp 90C, but 95 or 100 will stick nicer.
