Heated Bed Silicone Mount Spacers

I bought some silicone heated bed mounts to replace some of the aging springs on a few of my printers a while back, and during some recent unrelated upgrades, I decided to install some of them.

The mounts I bought were in a 16 pack that sell on Amazon for $8.99.  https://www.printables.com/model/929088-cable-clamp-for-comgrow-ender-3-direct-drive-extru

Of the 16 spacers included in the package, 12 are 18mm tall and 4 are 16mm tall.  The shorter 16mm tall mounts are intended for use with a cable strain relief.

While I have yet to install any of these on an Ender 3 machine, I suspect they are a perfect fit for those machines in their stock configuration without any adaptations.

I installed the first set, three 18mm mounts and one 16mm mount on my Tronxy XY-2 Pro, however, my Tronxy isn't using any strain relief mechanism on the left rear corner, so I made a 2mm spacer to compensate for that single short mount and am pleased thus far with that result.

More recently, I threw some upgrades into my CTC A10s, a CR-10 clone.  Because the A10s has much longer bed mounting screws and taller springs, I was unable to use them in the same fashion as with my Tronxy.  It may very well be that they would work the same, had I left the stock stepper motors for the Z axis on the A10s, but the motors I'm using are 6mm taller than stock, so the Z axis carriers would bottom out against the stepper motor mounts, so it was obvious I'd need for the bed mounts to be taller.

For the A10s I printed three 12mm tall spacers and one 14mm tall spacer for the corner that would have strain relief, had I not replaced the heated bed with one who's cabling is not soldered directly to the heated bed.

I've included all three spacers I'm using between the two machines I've installed silicone bed mounts to thus far.

These spacers print easily as oriented in the STL files without any need for supports, however, I would STRONGLY recommend printing them with 100% infill for a solid result.  I printed these in PETG, although they should work fine in any material since they're isolated from the beds heat by the silicone mounts.  Still, if you print in a heated chamber, you might consider printing these from a more heat resistant material.
