Anet A8 Igus Blocks by ContraJeddy

Last crawled date: 3 years, 1 month ago

I made these as the 3d printed blocks I had caused too much binding. These allow you to secure the IGUS bushing with 2 zip ties, rather than completely encompassing it.
The 2 versions present are as follows:
AnetA8BedIgusBlocks.stl: The version i have printed and am currently using. It works well, the bearings are held securely. The bed is a few mm higher than what i had, but I'm fine with that.
AnetA8BedIgusBlocksV2.stl: For added security, for those who are concerned about a bearing popping out, this should block them in, at either end, whilst they are secured with zip ties.
AnetA8BedIgusBlocksV3.stl: AS per the update below, i have added in a part that should hit the end stop instead of the bearing and keep things positioned correctly. I have also decreased the side of the mounting screw holes to ensure a tight fit when screwing - this can always be drilled out if they are too tight.
Note: I haven't printed AnetA8BedIgusBlocksV2.stl so not 100% sure if it works as intended.
I printed them on end and opted to not use supports as any Odd shaped holes helped the screws bite. A bit of super glue helped ensure this.
UPDATE 01/01/2018:
Just an FYI - I have found out that this has altered the position of my print bed, the Y end stop used to crash into the lower part of the block, however this is not on this model, which means that the bed goes back a few mm further until the bearing knocks it. This isn't a major issue if you never use your full Y dimension, or if you can alter your firmware. However on a stock A8 I believe this to be an issue. To this end, i have included V3, which should sort this out however as of this date I haven't had a change to test this yet. Let me know if it works!
