Belt Tensioner and Limit/Homing Switch Holder for V-Slot V3

thingiverse

I offer these printed on my website LaserUpgrades.com This is used to hold and tension the belts as well as hold the limit switches. This works with EleksExtra switches, generic switches like Ender 3 or plain old switches like those used in microwaves. This design also manages excess belt and protects the switches from being crashed into (no damage to switch) There are 4 limit/homing switches -X, +X, -Y, +Y. I prefer using 4 switches- 2 for homing and 2 for limit. These hard limit switches are better than setting soft limits in cases where the position gets reset or when steps are lost. The kit for the EleksExtra add-in board is on AliExpress. https://www.aliexpress.com/item/33004758373.html?spm=a2g0o.store_pc_home.productList_35657802.pic_5 Hardware needed: Qty 6 - M3 12mm long pan head screws (for belt clamp) Qty 6 M3 nuts (for belt clamp) Qty 6 M5 12mm socket head cap screws Qty 6 M5 T-nuts Qty 4 - M5 Nuts (for switches) Qty 4 - M5 10mm socket head cap screws (for switches these are part of the EleksExtra kit) The EleksExtra kit comes with only 3 limit switches, but I prefer 4. I had a second kit for the 4th. Unable to find other source to purchase only the switches. Designed to hold nuts tightly. Some nuts are different sizes. They are intended to be pressed in with a little force. If you have an issue you can heat stake (using soldering iron) or crazy glue nuts in position. I can also provide different size nut capture options if requested. You should print 3 of each pair File description BeltLimit_4_Eleks.STL- left and right pair for EleksExtra Switches BeltLimit_4_Generic.STL left and right pair for generic switches with 15.5mm between holes BeltLimit_4_Creality.STL left and right pair for Creality (Ender 3, 5, etc) switches with 15mm between holes BeltLimit_4_HoldersOnly.STL left and right pair without switches, just to hold the belts I printed with 0.2mm layer thickness, 3 layers, 15%infill, with supports.
