MP Voxel/FlashForge Adventurer 3 Spring-Steel PEI Bed Clips by kwelch007

These are bed clips for 170x170mm Spring Steel PEI print beds for the Monoprice Voxel or FlashForge Adventurer 3, such as you may find on AliExpress. Specifically, they are for the print beds WITHOUT the magnetic sheet backing. Magnetic sheets lose their magnetism over time when exposed to heat, so non-magnetic beds should last longer. I routinely get +/-0.2mm 9-point calibrations.
These clips are based on the Glass bed clip published by Northnet (https://www.thingiverse.com/thing:4838908) but have been highly modified and the models have been simplified to remove unnecessary vertices and sides. Many thanks to Nortnet for the starting point!
Print 8 x Short_Post+Clip (4 for the back of the build plate and 2 each for the sides,) and 1 x FrontClip. You'll notice that the clips can slide when attached, but require a bit of encouragement to do so. I've never had them slide while printing. I highly recommend printing them on their "sides" to avoid overhangs and the need for supports.
I printed early versions of these with PLA and used them to progress to PETG which seems far better for this application. The PLA resolution was as not accurate and would expand significantly from bed plate temp. Also, they wore out fairly quickly. I print with 0.10mm layer height, but you could probably get away with 0.18mm.
Before printing or doing 9-point calibration with these clips, I highly recommend doing a simple 1-point calibration without a plate and raising the height to 2mm+ to avoid damaging the plate or nozzle. When performing 9-Point calibration be sure that the clips on the right side are at the extents of the gap in the build plate edge or they will interfere with the fan shroud.
I highly recommend printing these in PETG, but you could use a PLA version early on to print your PETG versions with PLA (I did.)
